Tingnan natin. A very long wire is carrying a time-varyingt current given . An conducting loop is placed at distance from the wire as shown in the figure. The wire and the loop are lying on the same plane. What is the magnitude of the total emf induced on the loop?

(L)et's (C)alculate! A 120. [mH] inductor is connected in series to a 2.50 [nF] capacitor to form an LC circuit. The capacitor charge is $\sqrt{2}/2$ times its maximum charge at $t = 0$ and drops to zero if the current in the circuit is 1.50 [A]. What is the capacitor charge after two-thirds of its period of charge oscillation?

Tube Ienc.  A steady current flows in a long hollow cylindrical wire of inner radius and outer radius . This current, directed out of the page, is distributed across the cross-section of the cable following the current density , where is a positive constant and is the distance from the wire's axis. Within the hollow is another wire carrying a steady current of into the page. What is the net magnetic field magnitude at region ?

Shooting charge. A straight wire located at a distance below the -axis is carrying a steady current of to the -direction, and an electron is travelling to the direction with a constant velocity . At an instant where the electron is at , what is the net magnetic field at the origin?

Curb. Consider a current-carrying arc (see figure) with radius . If the wire carries a current and is immersed in a uniform magnetic field with strength directed out the page, what is the total magnetic force on the entire arc?
