The rotation of plane-polarized light traveling along the direction of one of these can be calculated using the Verdet constant.
The rotation of plane-polarized light traveling along the direction of one of these can be calculated using the Verdet constant. This quantity is equal to the curl of the vector potential, and a potential difference is created across a metal plate when it is applied perpendicular to the current; that phenomenon is known as the Hall effect. For a solenoid it is equal to the permeability constant times the number of turns times the current, which can be derived from Ampere's law. For 10 points, identify this counterpart of the electric field.
