The loop of wire with area of .2 m? shown is positioned in a uniform magnetic field. The magnetic field has a magnitude of 4 Tesla and is directed into the paper (-z or -k direction) as shown. The magnetic field decreases to .2 Tesla in .4 seconds. Calculate the emf induced in the loop by the changing magnetic flux. 四008 Indicate on the figure the direction of the current that is induced in the wire. Explain your reasoning for choosing the direction.
