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.
Explanation:
thanks
hope it will help you
Explanation:
electromagnets are magnet which is artificially made by passing electricity through magnetic substances.
They are used in generator to produce more electricity.
Used in Manglev trains
The number of turns in coil and strength of electricity passing through the coil are the factors in which they depend
