Problem 2: An experimenter in a physics lab has connected a loop of wire of
radius quot;aquot; to a current meter. The student notices that when the loop is pulled
quickly from each side so that it snaps into two straight wires 3 current 10:: 5.00-mA is measured in the meter over a time twuect;:1.00.10’3.8. The radius of the loop is a:=1.200-m. The total resistance of the loop current
meter system is R0: 14.40.12. (A) Calculate the magnetic field that could be present. (B) Derive an expression for the charge passing through the current
meter that does not depend on time. Science
