A square wire loop with 2.00 m sides is perpendicular to a uniform magnetic field, with half
Question:
A square wire loop with 2.00 m sides is perpendicular to a uniform magnetic field, with half the area of the loop in the field as shown in Figure. The loop contains an ideal battery with emf ? = 20.0 V. If the magnitude of the field varies with time according to B = 0.0420 - 0.870t, with B in teslas and t in seconds, what are(a) The net emf in the circuit and(b) The direction of the (net) current around the loop

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.
