Question

Suggest three ways to produce a temporary magnetic field. Explain any one of them in detail.

Answer 1

The three ways of producing a temporary magnetic field are:

1. By making an electromagnet
2. Drawing the object near any strong magnet
3. Beating the object when it is present in a magnetic field.

Electromagnet:

1. An electromagnet is a magnet that works on electricity.
2. When the current is passed through a copper wire wound on an insulated soft iron core, it produces a magnetic field.
3. The magnetic field exists as long as the current is passed through the coil.
4. When the current is switched off, the magnetic field ceases to exist.
