Do You Know Neodymium Magnets Are Used For?
Neodymium magnets are a rare earth magnet, and known for their strength of power. When handled improperly, they can pose serious dangers. Often referred to as neo magnet, NIB or NdFEB, neodymium rare earth magnets are permanent magnets composed of an alloy of neodymium, boron and iron.
Of late, this magnet holds the title for being the strongest type of permanent magnet. It also has a metallic appearance. The applications of neodymium are many. They are used in several industrial areas, medicines and health, educational, and as handy tools.
Even the IT industry benefits from neodymium magnets in making computer hard drives, telephonic applications, television, video applications, and chip detectors. Companies that build generators rely heavily on neodymium to manufacture strong generators. The strength of generators depends on the power of the magnets used.
Manufacturers of oil filters use magnets so that the filters effective separate any iron fillings or other metal chips from the oil. Devices such as metal detectors contain the rare earth magnet.
Machines use them to hold down tarps to cover machinery and cars. You can use them also for making tool belts or for making the doll hold on to its pacifier. Designers for fashion accessories use neodymium magnets for making earrings and jewelry clasps. If you are looking for a magnet to keep name tags in place without having to stitch them on, you can rely on magnets.
Rare earth neodymium is used in the health industry, for alleviating symptoms and relieving pain caused by health issues like arthritis. These permanent magnets have healing abilities and are often called healing magnets.
They are also used in manufacturing Magnetic Resonance Imaging scanning machines. During space flights, NASA uses these rare earth magnets so astronauts can maintain muscle tone.
They are used for experimentation and research purposes. Neodymium magnets are small in size but enormous in its strength, making it convenient to carry anywhere and anytime. Also, because of its small size, toy industries use this magnet to make kid and adults toys.
There are many characteristics of neodymium to differentiate it from other magnets. It has a remarkably high resistance to demagnetization thanks to its natural attribute of being the strongest permanent magnet. Unlike the other types of magnet, the rare earth neodymium is affordable. There are two reasons why so many industries use this magnet.
Neodymium magnets require low working temperature for heat applications. If the temperature is set to high degree, they can easily catch fire. Neodymium inspired new applications in areas where magnets were not used.
What is the minimum distance to safely have a neodymium magnet away from electronics?
What is the minimum distance to safely have a neodymium magnet away from electronics? The neodymium magnet is 2” x 2” x 1” and is grade N42.
It won’t have any effect on any electronics unless they involve something magnetic, like a hard disk, or an electron beam, like a CRT. In the HD case, a few inches should be enough. For a CRT, you may need a foot or so.

Why does a neodymium magnet vibrate when passed through a detector that looks like the things at stores?
I have gotten a neodymium magnet from a kid in my high school and when I passed through the detector (I think it is a medal detector.) it started to vibrate in my hand. I was wondering what causes this. I think it is from magnets or whatever is in the devises that were on either side of me but I’m not sure.
How do i unglue a neodymium magnet from its casing?
i have extracted the neodymium magnet found in hard drives,but how do i take it out of its casing without demagnetizing it?
thank u!
How much stronger is a neodymium magnet compared to a ferrite magnet?
How many times stronger is the neodymium than the ferrite? I know there’s different qualities of each but Im asking on average, for the same dimension magnet.
These detection systems generate a weak magnetic field which induces an alternating magnetic field in security tags–detecting a specific change in field if present. A neodymium magnet has a very strong field and is likely to give a vigorous response as it attempts to aline poles which are alternating polarity. Some systems use radio waves to induce a field in the security tag and would not likely cause any response in a magnet.

magnets will most loose the magnetization from heat but very high heat if you dont break it and heat you will have the same strength magnet when you remove it but its going to be hard to do so
It depends on the composition. Ferrites can have a stronger field than neodymium magnets.

Can I use round neodymium magnet with a hole in the middle to make a DC Motors?
I’m making a DC motor for my science fair project and I did everything I am supposed to to make it work but my motor still does not work. Everything seems fine like Im using magnet wire, a neodymium magnet, paper clips that conduct electricity, alligator clips and a D cell battery but yet it still does not work. I was just wondering if it had something to do with the hole in the middle of the neodymium magnet?
The hole will not affect the operation.
Carefully rotate your motor, and ensure the battery power disconnects before the rotor reaches magnet centre.
Such a simple motor will probably need a push to make it run.
