According to Faraday's law of electromagnetic induction, the induced e.m.f depends upon
Correct answer: D. Rate of change of magnetic flux
- A. Minimum magnetic flux
- B. Maximum magnetic flux
- C. Change in magnetic flux
- D. Rate of change of magnetic flux
Explanation
Faraday's law states that a current will be induced in a conductor which is exposed to a changing magnetic field.Any change in the magnetic field of a coil of wire will cause an emf to be induced in the coil. This emf induced is called induced emf and if the conductor circuit is closed, the current will also circulate through the circuit and this current is called induced current.Method to change the magnetic field:By moving a magnet towards or away from the coilBy moving the coil into or out of the magnetic fieldBy changing the area of a coil placed in the magnetic fieldBy rotating the coil relative to the magnet

About Electromagnetism
Magnetic flux density and magnetic flux describe the strength of a magnetic field and the field passing through a surface. A charged particle moving through a magnetic field experiences a force perpendicular to its velocity and may follow circular or helical motion, depending on the angle between velocity and field.
