Question

Mention the Physical Signature of Lenz’s law with an example.

Answer 1

Hint
Lenz's law states that the induced electric current flows in a direction such that the current opposes the change that is induced in it. The EMF induced is totally based on change in the flux produced which is caused by change in movement of magnet or it’s change in magnetic behavior according to the distance.

Complete Step By Step Solution
Let’s begin with what is Len’s law and How it is an important concept in electromagnetism. It States that when a voltage is Created by a change in flux which is magnetic. The induced EMF is created. The induced voltage must create a current whose magnetic field is in opposite to the change which Produces it.
The main significance is that it gives the magnitude and direction of the Electric Current induced in the coil due to change in Magnetic flux thought that coil.
Let’s take an example over here, if we move a magnet near a wire that will create a magnetic field which will eventually oppose the motion of the magnet. It can be also used to find the direction of the current. It would be created in wire, which opposes the motion of the magnet. It is causing the current flow or we can say electron flow.
We can take another example, thrusting a pole of a permanent bar Magnet. Through a coil of wire. When the north pole of the bar magnet approaches the coil nearest the pole of the bar magnet itself a north pole is opposite. Approaching bar magnet. Upon withdrawing induced EMF reverses itself and the near side coil becomes the south pole to produce attracting force on the bar Magnet.

Note
We should know the principle of lenz law and how it works in real life with practical form. Lens law can be explored using PhET simulation. Connecting the bulb with the coil and movement of magnet will create a flux. Eventually, it helps to create electricity and glow in a bulb.
