Chapter 9, Problem 9.8P

A perfectly conducting filament is formed into a circular ling of radius a. At one point, a resistance R is inserted into the circuit and at another a battery of voltage V0 is inserted. Assume that the loop current itself produces negligible magnetic field. (a) Apply Faraday’s law, Eq. (4)= evaluating each side of the equation carefully and independently to show the equality; (b) repeat part a: assuming the battery is removed the ring is closed again, and a linearly increasing B field is applied in a direction normal to the loop surface.

The magnetic core in Figure 3. has a mean core length of 80 cm, and its uniform cross-sectional area is 10 cm?. The relative permeability of the core is 1,500, and an AC voltage source e(t) =60 cos(120 t )V is connected across the coil of N = 100 turns. Obtain an expression fo n the core and the current in the coil.
Induced voltage acts like a resistance to hinder the flow of current through an inductor.  True or False It is often more desieable to the conductor instead of the magnetic field.  True or False
An electromagnet shown below has a cross section area of 10 cm2 with a mean length of iron path of 100cm and mean length of airgap is 0.4cm . It is excited by a coil of 1000 turns of conductor windings. When a current of 1A is provided to the coil and the relative permeability of iron is 1300, then find the magnetic flux in the circuit.
