4.51 cm, are connected by a circular arc that has a central angle 0 and runs along the circumference of the circle. The connecting arc
and the two straight sections all lie in the same plane. If B = 0 at the center of the circle, what is 0?

- Two long straight current-carrying wires are lined up parallel to one another in vacuum at a distance d. Currents of I and I2 flow through the wires, both in the same direction generating the field of BM at a midpoint between them. Write down an expression for BM in terms of the currents running in each of the wires. Assume vacuum permeability µo = 1.

Pleasearrow_forwardYou are given a hollow copper cylinder with inner radius a and outer radius 3a. The cylinder's length is 200a and its electrical resistance to current flowing down its length is R. To test its suitability for use in a circuit, you connect the ends of the cylinder to a voltage source, causing a current I to flow down the length of the cylinder. The current is spread uniformly over the cylinder's cross section. You are interested in knowing the strength of the magnetic field that the current produces within the solid part of the cylinder, at a radius 2a from the cylinder axis. But since it's not easy to insert a magnetic-field probe into the solid metal, you decide instead to measure the field at a point outside the cylinder where the field should be as strong as at radius 2a. Part A At what distance from the axis of the cylinder should you place the probe?arrow_forwardAmpere's Law 2. Figure 4 shows a cross-sectional view of a coaxial cable.
