Question

Faraday's Law is based on the concept that:

stationary magnetic fields will induce a current in a closed loop of wire.

accelerating electric current generates light.

electric current generates a magnetic field.

changing magnetic fields will induce a current in a closed loop of wire.

stationary magnetic fields will induce a current in a closed loop of wire.

accelerating electric current generates light.

electric current generates a magnetic field.

changing magnetic fields will induce a current in a closed loop of wire.

Explanation / Answer

Faradays law states that indcued emf across a conductor is always equivakent to the rate at which magneic flux on the conductor changes

i.e induced emf = - d(phi)/dt

-ve sign appears due to lenz laws

i.e the relaticve motion of a magnet and condcutor will induced emf which in turn incued curreent in the wire

so answer is changing magnetic fields will induce a current in a closed loop of wire.
