Chapter 31, Problem 31.77AP
A long, straight wire carries a current given by I = Imax sin (ωt + ϕ). The wire lies in the plane of a rectangular coil of N turns of wire as shown in Figure P30.45. The quantities Imax, ω, and ϕ are all constants. Assume Imax = 50.0 A, ω = 200π s−1, N = 100, h = ω = 5.00 cm, and L = 20.0 cm. Determine the emf induced in the coil by the magnetic field created by the current in the straight wire.

A long solenoid has n = 400 turns per meter and carries a current given by I = 30.0(1 −e−1.60t), where I is in amperes and t is in seconds. Inside the solenoid and coaxial with it is a coil that has a radius of R = 6.00 cm and consists of a total of N = 250 turns of fine wire (Fig. P30.4). What emf is induced in the coil by the changing current?
Consider a coil with an area of 0.1 m2 and 17 turns placed in a magnetic field that is perpendicular to the plane of the coil. The magnitude of the field varies with time as B=0.52*exp(-t/2), where B is in teslas and t is in seconds. What is the value of the generated EMF at t=2.41 s?

- 30. A short wire runs along an x axis from x = a to x = -a (Figure P30.30). At t = 0, there is a small sphere carry- ing charge +9o at x = a and a small sphere carrying charge -9o at x = -a. As the spheres discharge and a current is established in the wire, show that, for t>0, the generalized form of Ampère's law (Eq. 30.13) and the Biot-Savart law (Eq. 28.12) give the same result for the magnitude of the mag- netic field a distance b up the y axis. (Hint: Obtain the elec- tric flux through a circular disk in the yz plane, centered at the origin. Because the electric field is not constant over the surface of the disk, you must divide the disk into a nested set of rings of various radii and integrate. A representative ring should have radius r and radial extent dr.) •.. Figure P30.30 b -90arrow_forwardμ_0 = 4π×10^(−7) T.m/Aarrow_forwardCan you solve #61 in the picture below?arrow_forward
