I. The below image represents a conducting wire, with a circular loop of radius 20 cm. The resistor in this configuration is rated at 5 N. Initially, a magnetic field is set at 12 µT, and oriented out of the page. Over the course of At =0.2 seconds, the field is increased to 21 µT. Note: for this exercise, treat this object as a perfect, closed circle, and ignore any contribution to the area or flux from the bottom part with the resistor. a) What is the magnitude and direction of the current induced in the loop due to the increased magnetic field? b) After the 0.2 seconds have elapsed and the magnetic field has stabilized at its increased value, the loop is slowly pulled out of the field. What is the direction of the current induced by this process. Explain.
