Question

The north pole of a long horizontal bar magnet is being brought closer to a vertical conducting plane along the perpendicular direction. The direction of the induced current in the conducting plane will be

• A. Horizontal
• B. Vertical
• C. Clockwise
• D. Anticlockwise

Answer 1

The correct option is D

Anticlockwise

1. According to Fleming's Right-Hand Rule, if we arrange our right hand's thumb, forefinger, and middle finger perpendicular to one another, the thumb will point in the direction of the magnetic force, and the forefinger will point in the direction of the magnetic field, and the middle finger will point in the direction of the current.

1. If the thumb, index finger, and middle finger are arranged according to Fleming's right-hand rule then they represent magnetic force, magnetic field, and induced current respectively.
2. So, using this law it can be concluded that the induced current will flow in an anticlockwise direction via the conducting plane.

Hence, option D is the correct answer.
