which way is the induced emf (or induced current) in the
question below?
A uniform magnetic field points directly into your paper (make a sketch). A 7 turn coil of wire with a radius of 14.2 cm lies in the plane of the paper. Over a period of 0.00035 seconds, the field is increased from 0.300 T to 1.10 T. How much emf is induced in the coil while B is changing?

For the setup below, we can see that coil A will generate a magnetic field that coil B will see. As long as the field is constant, no induced magnetic fields will be produced by coil B. However, if the field from A changes, then coil B will induce a voltage which induces a current which induces a magnetic field to oppose any change. So what will be the direction of the current if: The switch on A is opened...
