What is the principle on which an electromagnet is made?
The correct option is C Magnetic effect of electric current
An electromagnet is made up of a soft iron core wrapped by a coil and a current is passed through it. This flow of current through the coil makes an electromagnet having north and south pole.
An electromagnet operates based on the supply of electricity.
A simple electromagnet is created by wrapping conductive wire in tight coils around a core (refer to the diagram). The magnetic force is generated just like a permanent magnet when the electricity is turned on and stops when the electrical current is disconnected. The magnetic field strength of this electromagnet (iron nail) is proportional to the magnitude of the current flowing in the wire of the electromagnet
