Magnetic flux is defined as a measure of magnetism through a specific area or surface. This Demonstration allows the user to visualize changes in magnetic flux through a loop of wire by changing the magnetic field and the loop's radius and location.
The magnetic flux is found by taking the surface integral of the magnetic field over the loop of wire. The loop is modeled by a circular cut-out of the plane , where is the vertical location of the loop relative to the axes. The popup menu contains uniform and nonuniform magnetic fields. The plot label displays the calculated magnetic flux through the loop of wire.
