Lenz's law in electromagnetic induction is direct consequence of law of conservation of:
Correct answer: A. Energy
- A. Energy
- B. Charge
- C. Momentum
- D. Mass
Explanation
Lenz's law states that induced current flows in a direction that opposes change in magnetic flux.This opposition prevents the system from producing energy out of nothing.Thus it directly follows principle of conservation of energy.

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.
