Howard Johnson Magnetic Motor - Generate Your Own Electricity As Featured in Science & Mechanics
Author: Scott Harris
The Howard Johnson magnetic motor is considered to be perhaps the most pioneering invention in magnetic motor technology. Thanks to Johnson's work, many others have followed in his footsteps to the degree that it is now possible to use a similar device to generate your own electricity at home. Find out more about Johnson's magnetic motor and see how you can benefit from this technology yourself in order to generate enough electricity to power your home.
How Does It Work?
Like all magnetic motors, the Johnson motor uses a series of strategically placed magnets around a rotor. What makes the Johnson motor unique is that is uses two sets of magnets.
The first set of magnets, known as stator magnets, are fixed to the inside of a drum/cylinder shaped casing. A rotating drum is placed inside the casing and this is effectively the rotor. Attached to this rotating drum are another set of magnets called armature magnets.
After an initial input is put into the system, the unique configuration of the magnets ensures that the motion is self-sustaining. Electricity is generated via a belt (like the one under the hood of your car) that is connected to a conventional electricity generator.
The Howard Johnson magnetic motor is currently protected by US patent law.
Other Magnetic Motors
Much development of these motors has been carried out in the last three decades by a handful of dedicated pioneers who have not been paid for their experimental work.
Most are similar in concept: they use a series of strategically placed magnets and drive a rotor of some sort. Where they differ is in the configuration of the magnets, driven by a need for these devices to fulfil many different types of commercial application.
If all you want is a basic device to power a home then you can simply make one yourself (or wait 5 years for the first domestic device). These days you can buy a set of instructions and plans that will save you the headache of trial and error and allow you to make a device capable of powering your home with nothing more than a few parts easily sourced locally.

has anyone tried to build the magnetic motors shown on you tube?
do you know a link of a good design i could build, that you have built and know it works
Y’know, I look at them and look at them, and I think, “maybe, just maybe” and then rationale kicks in, and I start seeing why they won’t work, much as I wish such a thing could. Sorry, I don’t believe you’ll EVER find one that actually works should you build it. But I would love for someone to prove me wrong. Really.
HELP! Questions about a motor made from a battery, paper clips, electric tape, magnets, and a loop.?
Thank you for taking the time to read this question/questions. I have this lab I did, but I do not know much about motors. If I could answer these questions, I can write my lab report well. Please, if you can answer any of these questions do so. Thank you so much!
I know some of these questions require a sketch or futher experimentation.
The motor looks like this:

Write out three criteria you will use to assess the effectiveness of your motor design. Examples may include, RPMmax, RPMstable, estimated torque on the loop, etc.
Time how long can you get the motor to run before it falls off the cradle? When you get to the next two steps below, time it under each coil condition. This is a measure of the motors operating stability.
Turn the coil slowly by hand and feel the magnetic attraction at each position of the coil. Make drawings showing the different coil positions and describe how the attractions vary at each position.
Adjusting the phase angle of the motor so that it will operate in a vertical position. This involves removing a different area of insulation from the partially bared tail of the coil. Research what the phase angle of a motor is, and sketch a design for this new motor with a nearly vertical operating position.
Different shaped coils. We know that the magnetic field inside a closed current loop will be zero regardless. So any shape should spin like a motor. What shape works best. Reconfigure your motor rotor shape and write down the details of how each new shape works or failed to work. Try to determine if a circle really is the best shape? Try squares, ovals, triangles, etc. Make certain you sketch each coils configuration you try, with a short summary of the results included with them in your lab write up.
Varying the number of turns of wire in the coil. Qualitatively we assume this would affect the motors efficiency. Develop a hypothesis to evaluate this and conduct an experiment to determine how the number of turns affects this motor. Is there any magic to the seven initial turns? What is the science behind the optimal number of turns you discovered? Does even or odd number of turns work more effectively than an even number of turns? Does the number of turns determine the speed? Include the different coils turns you try in a table, try at least three different coil sets, and describe the results in your table.
Speed and RPM. Write out a scientific method for determining the speed of the motor (in RPM)?
Write down, sketch out changes in design, that would enable your motor to do work?
I am not able to obtain the materials to do the other parts of the lab. I am kind of annoyed because I know my teacher just got this lab online and didn’t even read the questions before assigning the lab. If he had read the questions, he would have seen that we do not have enough time to do all of the lab and the questions. Hopefully, I can get him to give us another lab day to do the other parts of the experiment.
I suggest that you actually perform the lab experiments and write it up. Any good teacher will know when the assigned research was not done by whom it was assigned to. Do the experiments, it’s the only way you’ll learn…
Could a magnetic vortex be generated?
in relation to an AC motor design opperating at the frequency of (visible) light (400-790THz))
was thinking probibly using soe sort of teslacoil. the qustion was more theoretical than practical.
the fastest resonators i am aware of are in the 260GHz range
one thaught i had was to use magnetic trapping to levitate a chunk of superconductor in a vacume… that would reduce friction im not bothered about a shaft teh idea is about the vortex. many thanks to demondoppel for a well thaught through reply
and just how could you manage to get a motor to rotate at that speed?
Back emf represents the output of the motor. So you want to maximize it to get the best efficiency, not minimize it. If a 12V motor is unloaded, then it is the back emf that minimizes the current drain from the 12V supply.
There is no such thing as a “magnetic transference inductor”, which probably accounts for the paucity of information on the internet. But here is a site for designing electromagnets.

You need a lot of engineering knowledge to design electromagnets or motors. There is an excellent textbook on the subject by Bleany and Bleany.
I am looking for the best induction coil design to limit back emf.?
I am working on a motor design that can regenerate at least a portion of electricity that it uses in order improve motor efficiency. My problem is that I have limited experience in induction coils. The internet has almost completely useless for information so I need prospective from an engineer or someone strong in physics. Essentially I am trying to limit the effects of back emf on the permanent magnetics that I am using. I have though about both utilizing an L shaped coil along with a permanent ring magnet at end of the coil and a capacitor or 2 to minimize the back emf. Also I know how the theoretical “optimal condition” vs actual condition works for a solenoid strength. Are there any GOOD formulas for actual results and a how to for winding magnetic transference inductors? Any help offered would be greatly appreciated.
Magnetic Levitating vehicle assignment?
I am designing a Magnetic Levitating (MagLev) vehicle for tech. I want to know if anybody has any ideas on what type of materials i should use and any type of structure or design my vehicle should be. The vehicle will run on a electrical track providing power.
Restrictions:
no longer than 15 cm
width must be about 6 cm—to fit on track
wires must not sit on top of track, they must slide along the inside of the track
TEACHER WILL PROVIDE=motor, 4 magnets and a propellar
Thx and all helpful answers appreciated
Assuming that the teacher provides the track, and you build the vehicle, here’s what to do:
1) Fashion your vehicle out of the lightest material available. You can build a balsa wood model. I’d carve my vehicle out of styrofoam.
2) Create an aero-dynamic shape, like the monorail cars at Disneyland. Make the vehicle as long & thin as possible.
3) Pay special attention to the area where your vehicle interfaces with the track. I would carve a slot in the bottom of the vehicle. Put 2 magnets in the bottom, to elevate the vehicle, and the other 2 magnets on the inner left & right of the underside. These will “surround” the track, thereby keeping your vehicle centered.
4) Embed the motor inside the vehicle, with the propellor in back. Give the propellor a long axel so it can rotate freely and quickly. Reverse the wires on the motor, to get the propellor to spin in the opposite direction.
5) Put tiny wings on the vehicle, like a formula 1 racer, in case it’s not steady on the track. Position the magnets properly and use additional weights to balance it.
