(a) According to ampere's law the line ingral of the magnetic field through a colsed loop is mu not times the sum of the current in the loop. mathematically
where the left hand side is giving the line integral of the magnetic field and I is the total current through the loop.
Consider an imaginaty loop of radius r with the current carrying wire at the center the magnitude of the field B is constant everywhere on the loop and the direction of the field is parallel to the loop hence the line integral is given ...
A current carrying wire induces EMF in a loop between a fixed pair of rails and moving straight wire. Five different parts are solved step by step and explained.
