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. At t = 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 V. Ignore the self-inductance of the circuit. νο...

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...
