Question

A straight conductor of length 2 m moves in a uniform magnetic field of induction 2.5 x `10^-3` T with a velocity. of 4 m/s in a direction perpendicular to its length and also perpendicular to the field. The e.m.f. induced between the ends of the conductor is ______.

Options

• `20 xx 10^-3` V

• `3.75 xx 10^-3` V

• `37.5 xx 10^-3` V

• `25 xx 10^-3` V

Answer 1

A straight conductor of length 2 m moves in a uniform magnetic field of induction 2.5 x `10^-3` T with a velocity. of 4 m/s in a direction perpendicular to its length and also perpendicular to the field. The e.m.f. induced between the ends of the conductor is ______.

Explanation:

e.m.f. induced between ends of conductor 

e = `"B"/"v"` = `2.5 xx 10^-3 xx 2 xx 4 = 20 xx 10^-3` V
