Introduction to the problem: P. P, is a circular path in the s-p plane with a radius R, p, is a rectangular path in the s-z plane, with dimensions d and h.. D distance from the wire P, is a rectangular path in the s-z plane, with dimensions d and h,-2h,, D distance from the wire z axis points up, s points radially away from the z axis, is tangent to the circular path An infinite wire with a radius R carries a current with a density given by the equation JJ(1) cos(wt), s≤R 10, s> R where J > 0 is a constant, & is a distance from the long axis of the wire in the radial direction, and the z-axis is along the long axis of the wire. The current is oscillating with the frequency w in time. Assume that the frequency of the current oscillations is small. a) What is the magnitude of the magnetic field inside the wire as a function of s. b) Select one: O a. B(s) = 40J cos(wt) O b.
