An induction stove heats a pot with a coil carrying an alternating current located beneath the pot (and without a hot surface).Can the stove surface be a conductor? Why won’t a coil carrying a direct current work?
Faraday's law of magnetic induction states that the voltage induced by a current running through a wire
directly relates to the number of loops in the wire and the area the wire makes. If both the number of loops
of wire and the area of the wire are both doubled, by what factor will the voltage produced increase?
(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?

- From time to time, transformers explode. If your neighborhood has ever lost power all at once, this is likely to be one of the reasons. To illuminate why this happens, consider the transformer box in your neighborhood: It needs to take the 7200 V from the power lines and transform it to 120 V, which you will use in your home. (a) If the secondary coil has 40 turns, how many turns does the primary coil have? (b) If the 7200 V coil and the 120 V coil are separated by a distance of 30 cm, calculate the electric field that exists between them. (c) How much energy is stored in this electric field, if the total volume enclosed between the transformer is 0.6 m³? Do you think this is enough to cause an explosion?

This massive increase in voltage is achieved through a transformer called the 'ignition coil'. A typical ignition coil has a primary with 300 turns wrapped around a radius of 2 cm over a linear distance of 15 cm . The secondary has 60,000 turns of wire over the same cylinder. The spark is generated when the current is suddenly shut off to the coil. Assuming that the magnetic field is uniform inside the primary and secondary, and that all of the magnetic field lines that go through the primary go through the secondary, what voltage is generated in the secondary coil if the current drops from 10 A to 0 A at a steady rate over the course of 50 mirco-seconds?
