Find the emf across points P and Q which are diametrically opposite points of a semicircular closed loop moving in a magnetic field as shown in figure. Also draw the electrical equivalence of each branch.

A flat coil as shown in . The total resistance of the loop and the wires connecting it to a sensitive ammeter is 0.50Ω. If the loop is suddenly collapsed by horizontal forces as shown in the shape of a spiral The plane of a square loop of wire edge length a = 0.200 m is perpendicualr to the Earth's magnetic field at a point where B = 15.0μT what is the total charge passing through the ammeter?
