Using the Biot-Savart law, determine the expression for theresultant magnetic field B, along the line x joiningtheir centers.Express the magnetic field in terms of the radius of the coilsR, the number of turns N, the current I. x, and thepermeability of free space, Ho-Evaluate the magnetic field B, at x = 4.500 cm (R) and x = 13.50 cm (R).B. (4.500)0.019IncorrectB, =TB. (13.50)=20.019Incorrect Helmholtz coils are frequently used in experimentsbecause they create a uniform magnetic field abouttheir central axis. For example, they aretraditionally used in the experiment for themeasurement of the charge-to-mass ratio of theelectron. Helmholtz coils are two coils separatedby a distance equal to their radius that carry equalcurrents in the same direction."Suppose the radius of the coils is R 18.00 cmand each coil carries a current of /== 11.50 A andhas N340.0 turns. The coils are in the yz planewhere one coil's center is at x = 0 the other coil'scenter is at x = R.-X=R00

At a point P on the center axis of a magnetic field created by a sufficiently long solenoid, we divide the magnetic field strength vector into a circular loop of the solenoid coil as shown below to add all the magnetic fields they create. (Let's simplify to continuous which isn't continuous). Complete this task to show that the magnetic field strength is "first image"at P point.

A long straight cylindrical shell has an inner radius R; and an outer radius Ro. It carries a current i, uniformly distributed over its cross section. A wire is parallel to the cylinder axis, in the hollow region (r < R;). The magnetic field is zero everywhere in the hollow region. We conclude that the wire: O is on the cylinder axis and carries current i in the same direction as the current in the shell may be anywhere in the hollow region but must be carrying current i in the direction opposite to that of the current in the shell may be anywhere in the hollow region but must be carrying current i in the same direction as the current in the shell is on the cylinder axis and carries current i in the direction opposite to that of the current in the shell O does not carry any current
