• B. a-g, b-h, c-f, d-e
• C. a-f, b-h, c-g, d-e
• D. a-h, b-g, c-e, d-f

Answer 1

Answer: (B)

a) Fleming's left hand rule is used to find the direction of force due to magnetic induction

b) Right hand thumb rule is used to find the directions of magnetic lines of force due to current

c) Biot-Savart law is used to find the magnitude and direction of magnetic induction

d) Fleming's right hand rule is used to find the direction of induced current
