Two coils A and B are separated by a certain distance. If a current of 4 A flows through A, a magnetic flux of 10–3 Wb passes through B (no current through B). If no current passes through A and a current of 2 A passes through B, then the flux through A is
- 5 × 10–3 Wb
- 4 × 10–4 Wb
- 5 × 10–4 Wb
- 2 × 10–3 Wb
Answer
(C) 5 × 10 –4 Wb
