Electromagnet is a strong magnetic force inside a solenoid.
It can be mostly used to magnetise a part of magnetic materials like a soft iron when placed in the coil.
If electric current is passed through a wire wound around a piece of soft iron, it behaves like a magnet. Those magnets are called as electromagnets.
Applications of electromagnets are as follows :
- Electric bell
- Electric motor
- Loudspeakers
