Magnetic field and magnetic flux

See attached file for full problem description. 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 du... click for more

Electromagnetic Theory Question

Answer only Question #1. See attached file for full problem description. A thundercloud has the charge distribution as shown on the diagram. Treat this distribution as two point charges, a negative charge of -30 C at the height of 2 km above the ground and a positive charge of +30 C at the height of 3 km. The presence of these charges induces charges on the ground. Assuming the ground is a conductor, it can be shown that the induced charges can be treated as a charge of +30 C at the depth of 2 km below ground level and a charge of -30 C at the depth of 3 km. Consider point P1, which is just above the ground directly below the thundercloud, and point P2, which is 1 km horizontally away f... click for more
