A coil of 100 turns and radius 2 cm is in a uniform magnetic field as shown below. The magnetic field changes with time according to the graph.
A coil in a uniform magnetic field.
- What is the emf induced around the coil?
- If the coil has a resistance of , what is the current in the coil?
- In what direction will current flow in the coil?
- What is the direction of the electric field (i.e. the curly electric field) that is induced by the changing magnetic field, at point P (which is located in a +z plane, out in front of the page)?
