Question

Which of the following actions will not make a magnet lose its magnetic properties?

2. Hammering a magnet
3. Passing electric current through a magnet
4. Heating a magnet

• A. Only 3
• B. 1 and 2
• C. 3 and 4
• D. Only 4

Answer 1

The correct option is A Only 3

If a magnet is heated, hammered, or dropped on the floor, its magnetism is destroyed (or it gets demagnetized). However, a magnet will not lose its properties when electric current is passed through it.
