Magnetic field in a region is equal to B. A loop of resistance R and radius r is lying in the field with the plane perpendicular to the field if the loop is turned by 180 degree. Find the charge which flows through a given cross section of the loop
Please find below the solution to the asked query:
The emf generated by in the loop due to magnetic field is .
Now if r is the radius of the loop then area is given by .
If I is the current through the loop we, then we have
So total charge flown through the circuit is given by
Here we are considering that the time taken to rotate 180 degree is T. Now we have
Using above value we get
