What will be the magnetic potential difference across the air gap of 2 cm length in magnetic field of 200 AT/m ?
Correct answer: B. 4 AT
- A. 2 AT
- B. 4 AT
- C. 6 AT
- D. 10 AT
Explanation
Magnetic potential difference, or mmf drop, is H multiplied by the gap length: 200 AT/m × 0.02 m = 4 AT. Hence option b is obtained.
