a. The current I goes along a long straight wire perpendicular to the conducting plane and spreads along it. Determine the magnetic field distribution.
b. A long wire with current I intersects the conducting plane in a direction perpendicular to it. The current flowing to the plane is I₀. Determine the distribution of the magnetic field in this system.
c. The coaxial cable enters the spherical plane as shown in the figure. Find the magnetic field induction in the entire space.
