1.	You have been provided with a solenoid AB. 1. What is the polarity at end A? 2. Give one advantage of an electromagnet over a permanent magnet.
Answer» 1. Polarity at the end A is NORTH pole . 2. An electromagnet’s strength can be increased by increasing the flow of current in the coil, which is not possible in case of a permanent magnet.
