Question

State lenz law . Explain by giving example that lenz's law is a consequence of conservatiin of enegy

Answer 1

Ello user !!!!!!!!

Here is your answer,

=======================================

Lenz's law states that the current induced in a circuit due to a change or a motion in a magnetic field is so directed as to oppose the change in flux and to exert a mechanical force opposing the motion.

If the magnet is not moved , no mechanical work is done , then no e.m.f. (thus no current) is induced in the coil i.e.,no electrical energy is produced .

Thus Lenz law is in accordance with the law of conservation of energy.

HOPE THIS HELPS YOUU :)

AND STAY BLESSED.

Answer:

$\mathtt \red{ \xcancel{\int ( \frac { 2 + 3 \cos x } { \sin ^ { 2 } x } ) d x}}$
