A wire with current flowing through it perpendicular to the page is shown (position is given in meters and the integral is given in 10-10 Tesla-meters). Also shown is a choice of two detectors that displays the integral, .
Choose a detector and observe readings. You may drag a detector from its original position if you wish. Use your reading(s) and Ampere's law to determine the current flowing through the wire.
Read the magnetic field at any point in the animation by a mouse-down. Enable B Field
Cannot use Detector A, -1.0mA from Detector B.
