Answer 2

Factors affecting the strength of an electromagnet and magnetizing a steel bar by electrical method.

Explanation:

• The nature of the core material, the strength of the current pass through the wire. The turns of wire used to pass the current and its structure are the reasons affects the strength of the electromagnet.
• The direct supply is given to Solenoid (copper wire made of turns) and a steel bar is placed inside the solenoid. When the current flows through the wire the strong magnetic field is produced.
