(a) What is the magnetic flux through the surface bounded by the circuit?
(b) What is the resistance of the circuit?
(c) What is the force on the rod due to the magnetic field? Give both the magnitude and direction of the force.
(d) Some time later, the rod is sliding in the y direction at 5.1 m/s. What is the resulting EMF induced in the circuit? Will the current in the circuit increase, decrease, or stay constant?
(e) Extra credit - Describe what happens next. Does the rod speed up, slow down, or continue at the same speed? What happens to the current in the circuit? Explain your reasoning. (Assume the rails are long enough so that the rod doesn't reach the ends.)
5. Circuit - A DC circuit with two batteries and two resistors
Battery 1 is 8V and battery 2 is 14V.
Resistor A has a resistance of 19 and resistor B has a resistance of 6.
(a) What is the current flowing in the circuit? Are the electrons that carry the current flowing clockwise or counterclockwise around the circuit?
(b) A wire is added connecting the top and the bottom of the circuit, as shown below. What will be the current flowing through this added wire? Be sure to indicate the direction of this current.
Resistor A
Battery 2
