- Electromagnetic Induction due to a Temporary Magnet
- Summary
- What’s Next?
In the previous segment, we learnt about electromagnetic induction due to the relative motion of a coil and a magnet. In this segment, let us understand electromagnetic induction due to a temporary magnet.
Can Current be induced using a temporary magnet?
- A solenoid is a long cylindrical coil containing a large number of close turns.
- When current flows through a solenoid, it acts as a temporary magnet.
- Consider the following arrangement in which a solenoid is kept near a coil as shown below. The solenoid is connected to a DC battery and a key. The coil is connected to a galvanometer. The number of turns in the solenoid will be more than that of the coil.
