Objective: Measure the induced voltage in a conductor made into a loop as it moves through a magnetic field
The change in magnetic flux that is needed to induce a voltage in a conductor loop can be caused by a movement of the loop. Such a situation results, for example, when a conductor loop orientated with its plane perpendicular to a homogeneous magnetic field is moved into the magnetic field or withdrawn from it at a constant velocity. In the first case the magnetic flux increases at a rate determined by the relevant parameters, whereas in the second case it decreases in a similar way. Therefore the induced voltages are of opposite signs.
