A flat circular loop having six turns and radius 9.0 cm is placed on a horizontal surface. The resistance of the wire is 25 Ohms. A 9V battery is attached to the wire, allowing for the flow of electrons.

a) What is the magnitude and direction of the magnetic field? Assume the horizontal surface is defined by the xy – plane

b) If the wire shorts out (causing the current to stop flowing) in 50ms, what is the induced emf?
