According to Lenz's law, the direction of which of the following is always so as to oppose the change which causes it?
Correct answer: B. Induced current
- A. Induced emf
- B. Induced current
- C. Magnetic flux
- D. magnetic induction
Explanation
The direction of induced current is always so as to oppose the change which causes the current Lenz's law refers to induced current not the induced emf.

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.
