Shown in the figure below is a rectangle of wire immersed in a magnetic field. The rectangle has length L = 2 meters, width w = 1 meters, and a resistance of R = 7 2. The magnetic field varies with time according to the equation: B(t) = 8t2 + 4+4 As a result of the varying field, a voltage and current will be established in the loop. W Resistance = R B-field into the screen Answer all of the following: . What is the FORMULA for the rate of change of magnetic field with time, dB dt . What is the FORMULA for the rate of change of magnetic flux with time, dQB dt . What is the voltage in the circuit at t=1.5 seconds? Volts . What is the current in the circuit at this same time? Amps
