A 0.4 meter long straight conductor moves in a magnetic field of magnetic induction `0.9 Wb//m^(2)` with a velocity of 7 m/sec. Calculate the emf induced in the conductor under the condition when it is maximum.

Options

A. 2.52 V
B. 25 V
C. 2.8 V
D. 63 V

Answer

A

Explanation

`v_("max") = B xx V xx l`
`= 0.9 xx 7 xx 0.4`
`= 2.52 V`
