.. The circular loop shown in the figure to the right lies in the z = 0 plane and has a radius of a=0.10 meter and a resistance of 5 ohms. Given that the magnetic flux density in the vicinity of the loop has a value of B=0.20 sin 10ta, Wb/mº, determine a) the flux flowing through the loop, b) the voltage across the loop opening, and e) the current flowing in the loop 10. An infinitely long current I flows on either side of a rectangular loop as shown in the figure at the left Determine an expression for the total magnetic flux that penetrates the loop, in terms of the variables given. Hint: use the following result for the flux due to a single infinitely long line current and assume that linearity holds for this problem. 11. A rod of mass 0.72 kg and radius 0.06 m rests on two parallel rails that are d -0.12 m apart and L 0.45 m long. The rod carries a current of 1 = 48 A. If it starts from rest, what is the speed of the rod as it leaves the rails if there is a uniform magnetic field of magnitude 0.24 T directed perpendicular to the rod and rails? Answer in units of m/s. 12 A capacitor of capacitance C= 500uF is charged to a voltage of 900 V and is then discharged through a resistance R = 200 kA when a switch is closed. (1) Find the initial charge stored in the capacitor. (ii) Find the initial discharge current when the switch is closed. (iii) Find the voltage across the capacitor in a time t = 25 s after the start of discharge. (iv) Find the time constant of this capacitor resistor network combination
