In the given diagram, the directions of the induced currents through the coils, when the magnet moves toward the right, are
Correct answer: B. B
- A. A
- B. B
- C. C
- D. D
Explanation
Coil 1:Current B → A = anticlockwise → north pole toward magnet ▪ Coil 2:Current D → C = clockwise → south pole toward magnet Option B is correct. Both polarities properly oppose the change in flux in accordance with Lenz's law.

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.
