Question

The figure shows an initially uncharged capacitor connected to a resistor, in a uniform magnetic field pointing into the page (-z direction). Choose which changes to the system would cause the top plate of the capacitor to become positively charged. Rotating the magnetic field 90 degree counterclockwise around the x axis (so that the field ends up pointing towards +y). Decreasing the magnetic field strength, Rotating the circuit 90 degree counterclockwise around the y axis, Reversing the direction of the magnetic field, Increasing the magnetic field strength. Rotating the circuit clockwise around the z axis.

Explanation / Answer

T magneticflux decreases current is clockwise
T   magneticflux decreases current is clockwise
T   magneticflux decreases current is clockwise
T reversing flux will cause clockwise current
F counter clockwise current
F no induced current
