Why is a permanent magnet hard to magnetize?
You cannot magnetize a permanent magnet because it is already magnetized.
What is the difference between soft and hard magnets?
A soft magnet's magnetic field can be broken easily. A hard magnet's magnetic field can not be broken easily.
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.

When does the magnetic domain in a magnet produce a weaker magnet?
heated or dropped on a hard surface
Where is the magnet in a computer?
The only magnet in a computer is the one that reads and writes data to the hard drive. It is located inside the hard drive. Older computers also have a similar magnet in theirfloppy drive.
