Question

An electromagnet works on the magnetic effect of _____________

Answer 1

1. An electromagnet works on the principle of the magnetic effect of electric current.
2. This means that when current is passed through the coil, it magnetizes the iron core of the electromagnet and thus it exhibits magnetic properties.
3. Hence, it is said that it works on the property of magnetic effect through electric current.

Hence, an electromagnet works on the magnetic effect of current.
