Question
When an electric current passes through a solenoid, it acts as a/an:
- Insulator
- Electric bell
- Resistor
- Bar magnet
Hint:
When electricity is passed through the solenoid, it acts as an electro magnet.
The correct answer is: Bar magnet
- The solenoid is a long coil containing a large number of close turns of insulated copper wire.
- An electromagnet is a magnet when current is passed through a wire wound on soft iron core it gets magnetized and behaves like magnet.
- When electricity is passed through the solenoid, it acts as an electro magnet.
- Hence it acts as an Bar Magnet
