Lenz's law of electromagnetic induction explains:
Correct answer: C. Direction of induced e.m.f
- A. The production of induced e.m.f
- B. Magnitude of induced e.m.f.
- C. Direction of induced e.m.f
- D. Both magnitude and direction of induced e.m.f
Explanation
Lenz's law prominently focuses on determining the direction of the induced emf. It states that the induced emf will always generate a magnetic field that opposes the change producing it. This principle helps determine the direction of the induced current or emf in a circuit due to changes in the magnetic field.

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.
