An infinitely long wire has a current i, as shown, where io is a known constant. Above the wire, a rod of mass m and resistance R slides without friction on resistance-free rails, which are in turn connected to a capacitor of capacitance C. Att = 0, the rod is a distance of L from the capacitor. Batman pushes on the rod to ensure that it moves at a constant velocity Vo. Ignore the self-inductance of the circuit. L VO...

This problem explores how a current-carrying wire can be accelerated by a magnetic field. You will use the ideas of magnetic flux and the EMF due to change of flux through a loop. Note that there is an involved follow-up part that will be shown once you have found the answer to Part B.A.) A conducting rod is free to slide on two parallel rails with negligible friction. At the right end of the rails, a voltage source of strength...
A solenoid made of magnet wire (#20 gauge) with 12.3 turns per cm is attached to a 536 Ω resistor and a 110 V DC source. The diameter of the solenoid is 1.8 cm and its length is 15 cm a. (5 points) What is the self-inductance of the solenoid? b. (5 points) The emf induced in the solenoid depends on a changing current. After a long time the current will stop changing, and the only voltage drop in the...
In the figure, a rectangular loop of wire with length a = 3.8 cm, width b = 2.2 cm, and resistance R = 0.70 mΩ is placed near an infinitely long wire carrying current I = 4.7 A. The loop is then moved away from the wire at a constant speed v = 3.9 mm/s, when the center of the loop is at distance r = 7.9 cm, what are (a) the magnitude of the magnetic flux through the loop...
Problem 2 (Current through Loop) A rectangular loop of dimensions / and w moves with a constant velocity v away from an infinitely long straight wire carrying a current I in the plane of the loop, as shown in Figure 10.9.6.

A long wire carries a current in the direction shown above. The current I varies linearly with time t as follows: I=ct, where c is a positive constant. The long wire is in the same plane as a square loop of wire of side b, as shown in the diagram. The side of the loop nearest the long wire is parallel to it and a distance a from it. The loop has a resistance R and is fixed in space. a. Determine...
