Lenz's Law

A movable wire is moved to the right, that causes an anti-clock-wise induced current as shown in the figure. The direction of magnetic induction in the region P points

Lenz 's law used to find out the direction of

Lenz's law is a consequence of the law of conservation of

The negative sign in Lenz's law indicates that the flow of current support the change in flux.

State and explain Lenz's law in accordance with principle of conservation of energy.

As shown in the above figure, a magnet is pushed towards a fixed ring along its axis until the magnet passes through the ring. Now, choose the correct statement from the following:

Electric circuit is composed of three conducting rods $\overline{\mathrm{M}\mathrm{O}},\overline{\mathrm{O}\mathrm{N}}$ & $\overline{\mathrm{P}\mathrm{Q}}$ as shown in figure. The resistance of the rods per unit length is known to be $\mathrm{\lambda }$. The rod $\overline{\mathrm{P}\mathrm{Q}}$ slides as shown in figure at a constant velocity $\mathrm{v}$ keeping it tilt angle relative to $\overline{\mathrm{O}\mathrm{N}}$ & $\overline{\mathrm{M}\mathrm{O}}$ fixed at $45°$. At each resistance the circuit is closed. The whole system is embedded in a uniform magnetic field $\mathrm{B}$, which is directed perpendicularly into the page. Then induced electric current is -
