Find the magnitude of the magnetic field at a distance (a) r=0. (b) r = 2.6 mm and (c) r=3.6 mm from the center.
WebMagnetic Field Inside a Conductor. The magnetic field inside a conductor with uniform current density J = I/πR 2 can be found with Ampere's Law.. Inside the conductor the magnetic field B increases linearly with r. Outside the conductor the magnetic field becomes that of a straight conductor and decreases with radius. Note that the expressions for … WebAll right, let’s do an example related to the current density. Let’s say the current density across a cylindrical conductor, the current density across a cylindrical conductor of radius big R, varies in magnitude according to J is equal to J0 times 1 minus little r, over big R. Where, little r is the distance from the central axis of the wire.
