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.

TrueFalse Rotating the circuit clockwise around the z axis.
TrueFalse Rotating the magnetic field 90° counterclockwise around the x axis (so that the field ends up pointing towards +y).
TrueFalse Increasing the magnetic field strength.
TrueFalse Rotating the circuit 90° counterclockwise around the y axis.
TrueFalse Decreasing the magnetic field strength.
TrueFalse Reversing the direction of the magnetic field.

    1. An electron moves in a circular path in the magnetic field of an electromagnet. The plune of the electron's Sicular path is parallel to the smooth vole faces of the electromagnet. In the region where the electron is moving the magnetic field is uniform and has magnitude 0,50 T. The electron moves with a speed of 1.5 x 10 m/s. a. If someone could observe the electron from the north pole of the electromagnet, would the electron inove clockwise...
