OBJECTIVE 

To know about how electromagnets work and about their properties. I too learnt a lot from this activity conducted in our class.

What is an electromagnet?

An electromagnet is a temporary magnet which keeps it magnetic property till electricity flows or the circuit is closed.

MATERIALS REQUIRED TO MAKE AN ELECTROMAGNET:-

  • Battery

  • Iron nail

  • Copper Wire 

  • Any metallic object.

PROCEDURE:-

  1. Coil the iron nail with copper wire.

  2. Remove a bit of the insulation from both the ends of the wire and attach it to the battery.

  3. Bring the iron nail which is coiled and attached to a battery near a metallic object.

  4. You will see that the metallic object is getting attracted toward the iron nail.

  5. This is because of the iron nail getting magnetized.

It works on the MAGNETIC EFFECT OF ELECTRIC CURRENT.

How can you increase the power of an electromagnet?

  • Increasing the number of coils.

  • Decreasing the distance between the coils.
