The N-S poles of electro magnet can identified by(A) Fleming right-hand rule (B) Fleming left-hand rule(C) Faraday induction rule(D) Lenz's rule

Answer»

Faraday's law of induction isa basiclaw of electromagnetismpredicting how a magnetic fieldwillinteract with an electric circuit to produce an electromotive force (EMF)—a phenomenon called electromagneticinduction.hence this law helps in determining the NS of magnet due to the deflection produced in the needle
