Six Common Questions About Hard Drive Magnets

Hard drive magnets, also known as disk drive magnets, are mainly used for mechanical hard drives. You may have some knowledge about them, and this article has compiled 6 common questions.

1. What material is the hard disk magnet?

The vast majority of magnets from mechanical hard drives (HDDs) are sintered neodymium iron boron (NdFeB) because the read and write heads of hard drives require high speed and precise positioning, so high-energy accumulation materials must be used. Friends who have disassembled the machine should know.

2. What is the magnetization method of hard disk magnets?

It is different from ordinary magnets in that the magnetic poles are not distributed on two surfaces, but on the same surface, for example, from left to right, gradually changing from N pole to S pole.

3. Will the hard disk magnet demagnetize?

Under normal circumstances, it is unlikely. Possible factors for demagnetization of magnets include exceeding the temperature resistance of the magnet, mechanical impact causing cracks, and strong reverse magnetic field impact.

4. What can hard disk magnets be reused for?

Using the super strong magnet in the hard drive to make a homemade fish tank cleaner

Search for metal pieces that have fallen to the ground

Demonstrate magnetic levitation

Create magnetic storage tools

5. Is the hard drive magnet N35 grade?

The grade of hard disk magnets is usually higher, usually using N38 or above. Compared to standard N35 magnets, they have higher surface magnetic fields and stronger magnetic forces.

6. How to remove the strong magnet from the hard drive?

The magnet is attached to the base with glue. The method to remove the magnet is to use two pliers to break the two ends of the base, and the magnet will come out by itself. Do not pry it directly with a hard object, it will break. It can be loosened and detached by using a glue remover or heating.

The above is an introduction to several common questions about disk drive magnets. Hard disk magnets are usually customized in a curved shape. If you have other questions or need to know the price of a certain magnet, you can send us an inquiry.
