A rectangular loop of wire has height h, width w, and resistance R.

A rectangular loop of wire has height h, width w, and resistance R. It is mounted on an insulating stand attached to a glider, which is free to move without friction on an airtrack. The combined mass of the wire and the glider is m, and it is initially moving to the right with speed v0. The loop then encounters a region where an external magnetic field B is directed into the page (away from you). Derive a formula for the magnitude of the initial induced current in the loop at the movement the front end of the loop enters the region containing the field. (Questions are found in files below)
