3. Figure 2 shows a conducting loop of area A in a uniform magnetic field of magnitude B pointing out of the page. The loop is connected to a light bulb. The circuit acts as a generator as it rotates about the x-axis with angular frequency w. OB A Figure 2 a) What is the magnetic flux Pg(t) through the loop as a function of time t? Express your answer in terms of B, A, w, and t. b) Using a starting equation, derive an expression for the emf, t) generated in the loop as a function of time t. Express your answer in terms of B, A, w, and t. c) At what frequency foulb does the light bulb emit flashes of light?

a) What is the magnitude of the magnetic field at point P if I1 = 12.1 A and I2 = 33.7 A, in T? b) What is the direction of the magnetic field at point P with repsect to the figure?
