Question #5 A. [1 point] Is Ampere’s valid for all closed paths surrounding current carrying conductor? If not, why? B. [4 points] Two identical semicircular arcs have radii ?1 = 7.8 ?? and ?2 = 5.8 ?? carry current ? = 0.281 ? and share the same center of curvature, C. (a) What are the magnitude and direction of net magnetic field at C? (b) If the direction of the current is reversed, what effect does it have on the magnetic field?

Expert Solution

Ampère’s law is valid for all closed paths surrounding a conductor, but it is not always convenient to calculate the line integral. There are many paths along which the integral is cumbersome to calculate, although not impossible. For example consider a circular path around but not coaxial with a long, straight current-carrying wire.
