Problem Solving 6: Calculating the Magnetic Field using Ampere’s Law OBJECTIVES 1. To find an expression for the magnetic field of a cylindrical current-carrying shell of inner radius a and outer radius b using Ampere’s Law. 2. To find an expression for the magnetic field of a slab of current using Ampere’s Law. oscillation driven by a finite thickness current sheet in a plasma with a magnetic field parallel to the sheet. They showed that the instability threshold and the frequency range ofunstable waves are markedly altered when the finite thickness of the current sheet is taken into account.

*Magnetic Field of an Infinite Current Sheet*Figure 9.1.4 Magnetic field lines due to an infinite wire carrying current I. In fact, the direction of the magnetic field due to a long straight wire can be determined by the right-hand rule (Figure 9.1.5). Figure 9.1.5 Direction of the magnetic field due to an infinite straight wire Oct 20, 2014 · Magnetic Field from Infinite Sheet of Current Dr. Eric Abraham. Consider an infinite conducting sheet lying in the yz-plane, as shown in the Figure (the y-axis comes out of the plane of the paper). Suppose the sheet is carrying a uniform current in the y direction, out of the plane of the paper. Let J s be the linear current density, i.e., the current per unit length measured along the z axis.
