Motional EMF
30. Induction and Inductance / Motional EMF / Problem 3
An aluminium rod of length 8.0 cm is moved through a magnetic field perpendicular to the rod, resulting in a potential difference of 0.040 V across the rod. Determine the strength and direction (inward or outward of the page) of the magnetic field in this scenario.
