A small circular loop of wire of radius 5.0 cm and resistance R = 1.8 10-3 Ω is centered inside a large circular loop of wire of radius 50 cm (see figure below). The larger loop, which initially carries a current I = 6.7 A, is cut and its current is reduced to zero over a time interval of 1.1 10-6 s. Find the average current in the smaller loop during this time interval. (The magnetic field of the larger loop is approximately constant over the smaller loop.) magnitude direction

Given:
The magnetic impact on moving electric charges, electric currents, and magnetic materials is described by a magnetic field, which is a vector field. In a magnetic field, a moving charge experiences a force that is perpendicular to both its own velocity and the magnetic field.
A magnetic field is a region in which magnetic force is exerted around a magnet, magnetic object, or electric charge. A magnetic field is an unseen region surrounding a magnetic item that may draw another magnetic object toward it or push another magnetic object away from it.
