| Motional EMF From Lorentz Force |
| The e.m.f, induced across the ends of a conductor due to its motion in a magnetic field is called motional e.m.f. It is produced due to the magnetic Lorentz force acting on the free electrons of the conductor. For a circuit shown in figure, if a conductor of length l moves with velocity v in a magnetic field B perpendicular to both its length and the direction of the magnetic field, then all the induced parametres are possible in the circuit. |

A) Fleming's left hand rule
B) Fleming's right hand rule
C) Ampere's rule
D) Right hand clasp rule.
Correct Answer: B
Solution :
Direction of current induced in a wire moving in a magnetic field is found by using Fleming's right hand rule.
