A flat square loop of wire is held in a uniform magnetic field in such a way that the plane defined by the loop is perpendicular to the field lines. The side length of the loop is a = 13.7 cm and the magnitude of the magnetic field is B = 2.36 x 10-1 T. (a) Calculate the magnetic flux through the loop. (2 marks) (b) The square loop of wire is then rotated so that the angle between the plane of the loop and the field lines is now 20.0. What is the angle between the normal to the loop and the field lines? (1 mark) (c) Calculate the new magnetic flux through the loop. (2 marks) (d) If the time required to rotate the square loop was At = 0.750 s, then what was the magnitude of the generated emf? (2 marks) (e) If the resistance of the circular loop of wire is R = 2.00 0, then what current was generated in the loop? (1 mark) X X X X X X X X X X X X X X X X B(8) 2. The plot below shows the voltage (solid line) and current (dashed line) in a device that is connected to an ac power supply. The maximum voltage is 36 V and the maximum current is 18 A. (a) What are the period, frequency, and angular frequency of the ac power supply? (3 marks) (b) What is the reactance of the device? (2 marks) (c) Is the device a capacitor or inductor? (1 mark) (d) If the device is a capacitor, then what is its capacitance? If the device is an inductor, then what is its inductance? (2 marks) 0.0050 0.010 0.015 0.020 time (s)
