A square loop of a conducting material of side 1 and resistance `tau` is dragged through a uniform magnetic field B with uniform velocity v keeping the plane of the loop perpendicular to the direction of the field. What is the current flowing through the loop?

Text Solution

Verified by Experts


emf induced in coil ` E = (d)/(dt) BA = B (d)/(dt) Ix`
`E = BI(d)/(dt) = Blv` volts
Current in loop `= E/R = (Blv)/R` ampere
