A coil lies flat on a table in a region where the magnetic field vector points straight up. The magnetic field vanishes suddenly. When viewed from above, what is the sense of the induced current in this coil as the field fades?

As shown in the figure, an electron is fired with a speed of 3.23 x 106 m/s through a hole in one of the two parallel plates and into the region between the plates separated by a distance of 0.26 m. There is a magnetic field in the region between the plates and, as shown, it is directed into the plane of the page (perpendicular to the velocity of the electron). Determine the magnitude of the magnetic field (in μT) so that the electron just misses colliding with the opposite plate.
