A 0.375m long metal bar is pulled at a steady velocity perpendicular to a 1.00 T

Question

A 0.375m long metal bar is pulled at a steady velocity perpendicular to a 1.00 T magnetic field. The bar rides on parallel metal rails connected through a 100 ohm resistor so the whole set up makes a complete circuit. If the circuit induces an emf of 5V how fast is the bar moving?

Explanation / Answer

E = BLv

5= 1*0.375*v

v = 13.33 m/s
