Question
Electromagnet loses its magnetic property when:
- Current is switched ON
- Heat is increased
- Current is switched OFF
- Current is very high
Hint:
- An electromagnet is a temporary magnet which behaves like a magnet when an electric current is passed through the insulated copper wire
The correct answer is: Current is switched OFF
- An electromagnet is a temporary magnet which behaves like a magnet when an electric current is passed through the insulated copper wire
- loses its magnetism when current is stopped.
- The magnetic field disappears when the current stops. or Switched off
