As shown in figure two identical conducting rings of radius \(r\) are placed in magnetic field. In figure (a) magnetic field increasing at the rate of \(0.3 T / s\) and in figure (b) magnetic field decreasing at the rate of \(0.2 T / s\). The direction of current in ring (a) and ring (b), when observe from top are ___________ .
- A Clockwise, Anticlockwise
- B Anticlockwise, Anticlockwise
- C Clockwise, Clockwise
- D Anticlockwise, Clockwise
Answer & Solution
Correct Answer
(B) Anticlockwise, Anticlockwise
Step-by-step Solution
Detailed explanation
For ring (a): Magnetic field (into page) increasing → Induced magnetic field (out of page) → Current is Anticlockwise. For ring (b): Magnetic field (out of page) decreasing → Induced magnetic field (out of page) → Current is Anticlockwise.
