Chapter 29.2, Problem 29.1GI
Would you expect to find a magnetic field between the capacitor plates in Fig. 29.2? Explain.
FIGURE 29.2 Four surfaces bounded by the same circular Ampèrian loop. Surface 1 is a flat, circular disk. The others are like soap bubbles in the process of being blown; they’re open at the left end, so if current does pass through a surface, it does so at the right end only.

A long, straight wire with a circular cross section of radius R carries a current I. Assume that the current density is not constant across the cross section of the wire, but rather varies as J=αr, where αα is a constant.
Q1. What is the direction of the magnetic field in the two regions given (r < R and r >R) using the Amperian equation.
I only want to know the direction of the magnetic field, nothing else.
Figure 1: CRT with coils in Helmholtz configuration.
The hot cathode emits electrons which are then accelerated through potential difference Vacc. When
the electrons enter the magnetic field B, which is perpendicular to their velocity, they move on a circular
path with radius r. The magnetic field is due to coils in Helmholtz configuration (2 coils separated
distance that equals their radius).
The magnetic field due to one of the coils with radius R, at a point on the axis distance z away from the
center of the coil, was found using the Biot-Savart law:
