Concept:Magnetization is the process of aligning magnetic domains inside a material to turn it into a magnet.
Explanation:Induction is a valid method.
It magnetizes a material by placing it near or in contact with a strong magnet.
It can also occur inside a current-carrying coil.
Stroking is another valid method.
It involves rubbing a permanent magnet along iron or steel in one direction repeatedly.
This aligns the magnetic domains uniformly.
Hitting is not a method of making magnets.
Hammering or dropping scrambles the aligned domains.
Hitting is actually used for demagnetization, not magnetization.
Key point: The methods of making magnets taught at JHS are stroking (single and double touch), induction and the electrical method. Hammering, heating and alternating current are methods of demagnetizing.
