Please suggest some experimental setup for Lenzs Law

Hi

Lenzs Law: When an emf is generated by a change in magnetic flux according to Faradays Law, the polarity of the induced emf is such that it produces a current whose magnetic field opposes the change which produces it. The induced magnetic field inside any loop of wire always acts to keep the magnetic flux in the loop constant. In the examples below, if the B field is increasing, the induced field acts in opposition to it. If it is decreasing, the induced field acts in the direction of the applied field to try to keep it constant.

When current flows through a coil or circuit,magnetic field is produced and hence a magnetic flux gets associated with it,when there is a change in the current flowing through the circuit,there will be a change in magnetic flux and thus current is formed,the direction of the induced emf  will be such that it always opposes the change due to which its produced.if current is increased the induced emf is set upmin such a way that it will decrease the induced current ie the ibnduced current produced due to to induced emf flows opposite to main current ,this type of induction is back emf
