Hard magnets are permanent magnets that do not require electricity to retain their magnetism and are not easily demagnetized. They are magnetically charged naturally and can be artificially, too.

What happens when magnet is hit hard?

Assuming it has a robust rigid construction so it doesn't break easily : Nothing. If it is hit hard or even dropped repeatedly however, it will put the atoms out of position and lose the magnetism


What is needle magnet?

A needle magnet is a type of small, strong magnet that is shaped like a needle. It is commonly used for picking up small metallic objects like pins, needles, or screws that are hard to reach or see. Needle magnets are also used in compasses to indicate direction.


What is another name for a permanent magnet?

Normally permanent magnets are those solid metallic ones we can play with so you can probably get away with calling them an (insert shape here) magnet. e.g. Bar Magnet. As for another name. I don't think it has one. You can't call them electromagnets!


What type of magnet is a Refrigerator magnet?

The term "refrigerator magnet" is ambiguous and may refer to any number of types of magnets. However, typically a refrigerator magnet is going to be relatively weak and made of the most inexpensive materials available. Hard refrigerator magnets are likely iron. Flexible refrigerator magnets are made of bonded ferrite powders; barium ferrite is among the most common. In general classification, a refrigerator magnet is a permanent magnet.


What is the difference between soft and hard magnets?

Soft magnets are easily magnetized and demagnetized, while hard magnets retain their magnetism once magnetized. Soft magnets have low coercivity and high permeability, making them suitable for applications like electromagnets. Hard magnets have high coercivity and are used in applications where a strong, lasting magnetic field is needed, such as in permanent magnets.
