Question
Electromagnets are special types of magnets in which magnetism is produced by:
- Frictional force
- Magnetic force
- Hydro Electricity
- Electric current
Hint:
- Electromagnets usually consist of wire wound into a coil.
The correct answer is: Electric current
- Electromagnets usually consist of wire wound into a coil.
- Electromagnetism is produced when an electrical current flows through a simple conductor such as a length of wire or cable, and as current passes along the whole of the conductor then a magnetic field is created along the whole of the conductor
- Hence an electromagnet is a type of magnet in which the magnetic field is produced by an electric current.
