A long solenoid (cross-sectional area = 1.5 x 10-6 m2, number of turns per unit length = 3587 turns/m) is bent into a circular shape so it looks like a doughnut. This wire-wound doughnut is called a toroid. Assume that the diameter of the solenoid is small compared to the radius of the toroid, which is 0.073 m. Find the emf induced in the toroid when the current decreases from 2.5 A to 1.1 A in a time of 0.15 s. Number i Units
The figure below shows a flexible loop of metal wire with a radius of 15.0 cm. It lies in a magnetic field pointing into the page with a magnitude of 0.140 T. A physicist grabs the loop at points A and B and rapidly pulls in opposite directions until the loop folds up, such that its area becomes zero. The change in area occurs in a span of 0.190 s. A What is the average induced emf (in mV) in the loop over this time span? mv

A 2-turn planer loop of flexible wire is placed inside a long solenoid of n turns per meter that carries a constant current I0 . The area A of the loop is changed by pulling on its sides while ensuring that the plane of the loop always remains perpendicular to the axis of the solenoid. If n = 500 turns per meter, I0 = 20 A, and A = 20 cm2, what is the emf induced in the loop when dA/dt = 100?
