(a) Define self and mutual induction. Give practical examples of both inductions. (b) A circular coil of wire with 450 turns and a radius of 8.5 cm is placed horizontally on a table. A uniform magnetic field pointing directly up is slowly turned on, such that the strength of the magnetic field can be expressed as a function of time as: B(t) = 0.03 (T /s?) x t. What is the total EMF in the coil as a function of time? In which direction does the current flow?
