Answer:
Explanation:
Potential difference is created when a long object of length l moves perpendicular to magnetic field . The potential difference created is
V = Blv where B is magnetic field , l is length and v is velocity of length l .
here V = 45 x 10⁻⁶ x 44000 x 1.2
= 2.376 volt .
b )
Electric field = V / l ; V is potential difference between length l .
= 2.376 / 44000
= 54 x 10⁻⁶ V/m
