Question

What is an electromagnet ? Give any three uses of electromagnet . Name two factors on which the strength of an eletromagnet depends .​

Answer 1

Answer:

The strength of an electromagnet depends on: The strength of the current passing through the coil, the greater the current, the greater the strength. This because the current increases there is more flow of electrons which in turn increases the magnetic field around it.

Answer 2

The strength of an electromagnet depends on: The strength of the current passing through the coil, the greater the current, the greater the strength. This because the current increases there is more flow of electrons which in turn increases the magnetic field around it.
