A rectangular loop with a slide wire of ...

A rectangular loop with a slide wire of length l is kept in a uniform magnetic field as shown in the figure. The resistance of slider is R. Neglecting self inductance of the loop find the current in the connector during its motion with a velocity v.

Text Solution

Verified by Experts

The Equivalent Circuit is The equivalent resistance of the circuit is
`R.=(R+(R_(1)R_(2))/(R_(1)+R_(2)))`

Hence the current in the connector is `i=(e)/(R.)" ":. i=(Blv(R_(1)+R_(2)))/((R R_(1)+R R_(2)+R_(1)R_(2)))`
