Problem 4: The circuit of figure is a square 20 cm on a side. a. What is the current flowing through the circuit? Mark direction of current as Icircuit. If the magnetic field increases steadily from 0 T to 0.50 T in 10 ms, b. What is the direction of induced current? Mark current as Iemf. c. Calculate the induced current. d. What is the net current in the resistor during this time of 10 ms? If the direction of the magnetic field changes, what will be net current in the resistor? 20 0 9.0 V
