Question
The material of the core of an electromagnet is generally:
- Aluminum
- Soft iron
- Copper
- Steel
Hint:
An electromagnet is a type of magnet in which the magnetic field is produced by an electric current
The correct answer is: Soft iron
- An electromagnet is a type of magnet in which the magnetic field is produced by an electric current. Electromagnets usually consist of wire wound into a coil.
- The material used for preparing an electromagnet is soft iron
- The soft iron bar acquires the magnetic properties only when an electric current flows through the solenoid and loses the magnetic properties as soon as the current is switched off. That's why soft iron is used as the core of the electromagnet
