Question
While doing the activity for the electromagnet, did you also notice that the wire ends got warm? Why would that happen?
✓
Answer
The wire ends get warm when current flows through the wires for some time. This happens due to the heating effect of electric current. Depending on the nature of the metals used as conductors, the conductors offer some resistance to the flow of the current. In the process, a part of the electric energy is converted into heat energy that warms the ends of the wires.
