Question

lenz law explain with example please

Answer 1

the changing magnetic field in the coil due to the change in current induces a current in the metal ring Lenz's law states that the magnetic field in the ring opposes the magnetic field of the coil and forces the ring to fly away

Answer 2

Lenz's law is a common way to understand how electromagnetic circuits obey Newton's third law and the conservation of energy. Lenz's lawis named after Heinrich Lenz, and it says: An induced electromotive force (emf) always gives rise to a current whose magnetic field opposes the change in orignal magentic flux.


There are 2 types of EMI:- mutual Induction and self induction
