Question

The following methods is used to magnetize a magnetic substance without touching it by a magnet​

Answer 1

This method involves simply placing the magnetic material (soft iron) close to a strong magnet without touching.

The soft iron bar becomes an induced magnet with the end nearer the magnet having opposite polarity to that of the magnet.

Hence, the soft iron bar is attracted and attached to the permanent magnet. Magnetic induction process reveals how magnetic materials can be attracted to magnets.

Induced magnetism is a temporary process. If the permanent magnet is removed, the magnetic material will usually lose its induced magnetism.
