Please wait for the animation to completely load.
The gray circle in the center represents a cross-section of a wire carrying current coming out of the computer screen (position is given in millimeters, 10-3 m, and magnetic field strength is given in millitesla, 10-3 T). The current is uniformly distributed through the wire. The black circle is an Amperian loop with a radius you can change with the slider. Restart.
