A uniform magnetic field B is perpendicular to the plane of a circular wire loop of radius
Question:
A uniform magnetic field B is perpendicular to the plane of a circular wire loop of radius r. The magnitude of the field varies with time according to B = B0e–t/τ, where B0 and τ are constants. Find an expression for the emf in the loop as a function of time.

A magnetic field is a vector field that describes the magnetic influence on moving electric charges, electric currents, and magnetic materials. A moving charge in a magnetic field experiences a force perpendicular to its own velocity and to the magnetic field. The video shows the practical implications of magnetic force around different objects.
