In your own words, explain why the presence of a ferromagnetic core increases the inductance of a coil. Calculate the inductance of a coil wound on a ferromagnetic cylinder of 2 mm diameter and 10 mm length. There are 200 turns on the coil and the relative permeability of the core is 600. How does a real inductor differ from an ideal component?
(a) A coil of conducting wire carries a current of i(t) = 16.0 sin(1.20 x 10³t), where i is in amperes and t is in seconds. A second coil is placed in close proximity to the first, and the mutual inductance of the coils is 160 pH. What is the peak emf (in V) in the second coil? V (b) What If? Which would lead to a larger peak emf in the second coil, a doubling of the mutual inductance or a doubling of the frequency with which the current in the first coil changes? O Doubling the mutual inductance would lead to a larger peak emf. O Doubling the frequency with which the current in the first coil changes would lead to a larger peak emf. O The two changes would each have the same effect.
