Question

In the previous problem, how long after switch S is closed until the magnetic field is stable? (a) 0.05 ms. (b) 0.25 ms. (c) 0.38 ms. (d) 0.42 ms. (e) 0.48 ms. (f) _______ Circle each of the FALSE statement(s) below. (a) integral E middot dA = q/E_ suggests that it is not possible to find isolated electric charges in nature. (b) A resistor stores energy in the electric and magnetic fields that surrounds it when an electric current exists in it. (c) When an electric current exists in an inductor, energy is stored in the magnetic field that surrounds it. (d) integral B middot ds = mu_0 (i + i_4)_ where i_d = (phi_E)/suggests that there is a connection between light and electric and magnetic fields. (e) integral B middot dA = 0 predicts that it is not possible to find an isolated north or an isolated south magnetic pole in nature. (f) integral E middot ds = d (phi_)/dt predicts that an electric field is produced by a changing magnetic flux. (g) In a circuit containing an inductor and capacitor and oscillations are taking place, energy is alternately transferred between the inductor and the capacitor. A piece of wire is bent in the shape shown (a 2.99 mm horizontal section and a three quarter circle section with radius 2.62 mm). Determine the magnetic field (magnitude and direction) at point P. The current i = 195 mA. Magnitude: ______ Direction: The figure shows a cross section of a 14.6 m long solid cylindrical conductor whose radius is 1.60 m. It carries a uniform current of 3.80 kA. Using Ampere's Law, determine the magnetic field at a distance of 1.30 m from the center. 3.80 kA ________ Direction:

Explanation / Answer

32. a) Isolated charges can be found in nature.

b) a resistor dissipates energy in the form of heat, light and maybe even some sound. It doesn't store any enegy.
