Question

Two parallel rails are connected together at one end by a resistance of R = 20.0 as shown in the diagram to the right. Across these two rails, which are L = 45.0 cm apart, there lies a conducting metal bar. The magnetic field is uniform, has a strength of B = 2.20 Tesla and is directed into the paper as shown. A force is applied to the metal bar so as to push the bar to the right with a velocity v = of 8.40 m/s. a What will be the resulting EMF in this circuit? b What will be the direction of the resulting conventional current flowing through this circuit? c What will be the magnitude of the resulting current? d How much force is being applied to this bar? e In what direction will the induced magnetic field point due to the induced current.

a What will be the resulting EMF in this circuit?
b What will be the direction of the resulting conventional
current flowing through this circuit?
c What will be the magnitude of the resulting current?
d How much force is being applied to this bar?
e In what direction will the induced magnetic field point due to
the induced current.
