EMF induced in a circuit according to Faraday's law depends on the
Correct answer: B. rate of change of magnetic flux
- A. maximum magnetic flux
- B. rate of change of magnetic flux
- C. change in magnetic flux
- D. None of these
Explanation
Faraday's law of electromagnetic induction states that the induced electromotive force (EMF) in a circuit is directly proportional to the rate of change of magnetic flux through the circuit. Mathematically, it is expressed as EMF = -dΦ/dt, where Φ is the magnetic flux.

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.
