Question

If you were able to keep the electromagnet that you created in your laboratory activity, what would be two possible uses for the electromagnet?

Answer 1

Picking up metals & making power

Answer 2

Answer:

Electric bells or buzzers

To separate iron and iron objects from a mixture

Explanation:

When a current is passed through current carrying coil with magnetic material at the center, magnetic field is produced. Thus, it acts as temporary magnet. It can be demagnetized by stopping the current. The strength of the magnetic field can be increased by increasing the number of loops and amount of current.

At home, the electromagnet can be used as a buzzer or electric bell. The electromagnet can be connected to a iron armature with a clapper. In the presence of magnetic field, the clapper strikes the bell as the iron armature is pulled towards the field.

The electromagnet can also be used to separate iron objects from a mixture, such as iron nails, clips, pins, needles etc.
