Question

Describe an experiment to show that a soft iron bar when placed near a strong magnet gets magnetized.

Answer 1

Dear Student,

Magnetic Induction is one of the ways making magnetic materials like steel and iron or soft iron bar into magnets. In other words, magnetic induction is a process of inducing magnetism in an ordinary piece of magnetic material.

• 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.
