  • What is an Electromagnet Definition Uses Working

    An electromagnet can be defined as a magnet which functions on electricity. Unlike a permanent magnet the strength of an electromagnet can be changed by changing the amount of electric current that flows through it. If the current flow is cut the property of magnetism ceases to exist. But this is also an advantage of the electromagnet over a
