"The direction of the induced current is always so as to oppose the change that causes the current", is _.
Correct answer: B. Lenz's Law
- A. Faraday's Law
- B. Lenz's Law
- C. Ohm's Law
- D. Kirchoff's Law
Explanation
Lenz' law states that, "The direction of induced current is always so as to oppose the change which causes the current."ε = -N dΦB/dtWhere,ε = Induced emf dΦB = change in magnetic flux N = No of turns in coil

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.
