An electric current is uniformly distributed throughout a long, straight wire that has a diameter of 50 mm. The current through the wire is 5.0A . Calculate the magnitude of the magnetic field 20 mm radially away from the wire center. Calculate the magnitude of the magnetic field 50 mm radially away from the wire center.

An infinitely long, straight, cylindrical wire of radius R carries a uniform current density J. Using symmetry and Ampere's law, find the magnitude and direction of the magnetic field at a point inside the wire. For the purposes of this problem, use a cylindrical coordinate system with the current in the +z-direction, as shown coming out of the screen in the top illustration. The radial r-coordinate of each point is the distance to the central axis of the wire, and...
