The current flowing through a circuit creates a magnetic field that is perpendicular to the direction of the current. The change in magnetic flux, which is a measure of the magnetic field passing through a surface, is directly related to the change in current or the change in the area of the surface. In general, an increase in current will result in an increase in the magnetic field and therefore an increase in the change in magnetic flux. Similarly, if the area through which the magnetic field passes changes, there will be a corresponding change in the magnetic flux. Therefore, the current and electric field are related to the change in magnetic flux in that they can directly impact the magnitude of the change in magnetic flux.
