A small metal ring is placed in a larger metal ring. Current flows in the clockwise direction in the large ring when the large ring is connected to an electrical cell. State and explain the direction of the induced current in the small ring.

A square loop of wire of side a contains a resistor R and a capacitor C. The loop sits in a time-varying magnetic filed B = -Bot, Bo > 0. a) Find the maximum amount of charge on the capacitor. b) Find the magnitude and the direction of the induced current in the loop once the capacitor reaches its maximun charge. B R 0 Figure 4: RC circuit in a magnetic field

Which of the following statements are true? Choose all that apply. A changing magnetic field will always induce a voltage. As current through an inductor decreases, the inductance remains constant. For an LR circuit, as R increases, & decreases. Transformers can simultaneously decrease voltage & decrease current. Generators transform electrical energy (electricity) into kinetic energy. The mks units for inductance are Wb.

A loop of wire is moving near a long, straight wire carrying a constant current I as shown in the figure below. (a) Determine the direction of the induced current in the loop as it moves away from the wire. clockwise counterclockwise     into the page out of the page (b) What would be the direction of the induced current in the loop if it were moving toward the wire? clockwise counterclockwise     into the page out of the page
