Question
A flat circular coil with 100 turns has a radius of 0.04 m and a resistance of 0.5 ohms. It is exposed to a changing magnetic field that is perpendicular to the coil. The rate at which the magnetic field is changing is ∆B/∆t=0.782(T/s).
a. Find the emf (voltage) induced in the coil.
b. What is the current in the coil?
c. Sketch a picture of the scenario and, based on your drawing, show the direction of the induced current
