1. Two circular coils of radius R each perpendicular to a common axis. The coil centers are a distance R apart and each coil carries a steady current I in the same direction. Show that magnetic field on the axis at a distance x from the center of one coil is
Show that are both zero at the point midway between the coils.
This means the magnetic field in the region midway between the coils is uniform. Coils in this configuration are called Helmholtz coils.
2. A loop of wire in a shape of a rectangular of width w and length L and a long, straight wire carrying a current I lie on a tabletop. Determine the magnetic flux through the loop due to the current I.© BrainMass Inc. brainmass.com June 3, 2020, 7:27 pm ad1c9bdddf
