You may recognize the figure below from an earlier homework. It, however, represents a very different physical situation: this is now a very long (infinite for our purposes) conducting wire in the form of a cylindrical shell. The inner radius of the shell a=2.2 mm and outer radius b=5.8 mm. The electric current I=9 A runs along this wire and is distributed uniformly throughout the shell cross-section. This current is the source of the magnetic field, which you will be...

Using Ampere’s Law, find the magnitude of the magnetic field at a point exterior to a coaxial cable, a distance of 24 mm from the central axis. The coaxial cable consists of a wire with radius r1=1.3 mm and surrounding that, a cylindrical shell with inner radius r2=2.5 mm and outer radius r3=3.3 mm. The wire and cylindrical shell carry equal currents (4.0 A) in opposite directions. Side questions: 1. does the outer radius matter? 2. what would you do...

(2 pt) A loop of wire forming an equilateral triangle carries a steady current I. a. Find the magnetic field at the center of loop of wire forming a triangle which carries a steady current I. Let R be the closest distance from the center to the sides the triangle. b. Compare your result to the magnetic field at the center of circle of radius R. In which case is the field greater? Qualitatively explain why.

Electricity and Magnetism: Will rate high
for correct solutions!
A circular thin wire loop of radius a=37.6 cm and total resistance R=0.188 12 is positioned in the (xy)-plane, where it is exposed to the external (applied) uniform magnetic field directed along the z- axis. Over some period of time t, the z-component of that field varies as Bextz(t)=Bo – at + ßt?, where Bo=1.852 T, a=9.8 T/s and B=6.481 T/s2. Right at the geometrical center of the loop circle, there...

The figure below shows a cross-section of a long (infinite for our purposes) solenoidal system consisting of two coaxial solenoids, of radii a=3.3 cm and b=22.9 cm. These solenoids have the same number n=10 cm-1 of the turns of the wire per unit length. The wire is common and fed by the time t-dependent current I(t)=Io.sin(29f.t) but in the opposite directions as illustrated in the figure. Here the current amplitude Io=24.5...
