![(e) Examine the coil diagram in Figure 4.4.
(i)
Explain how the flux density B in the core can be changed without altering the
core's or the coil's physical characteristics such as structure, number of turns, or
material properties.
(ii) Now suppose that Vin was originally 10V but suddenly changes to 20V at to, i.e.,
there is a source voltage step change at to. What will happen to the voltage and to
the magnetic flux in the coil at to and right after to. respectively?
Explain your answer, including a brief discussion of Lenz's and Faraday's law as
well as how (or whether) these laws determine what will happen to the coil's
voltage and magnetic flux. Assume that the coil has no winding resistance or
capacitance.
