Question: Consider a long straight wire carrying current +i in the +2 direction. The wire is surrounded by a thin cylindrical shell with radius R that

Consider a long straight wire carrying current +i in the +2 direction. The wire is surrounded by a thin cylindrical shell with radius R that carries current 2] in the opposite, -z direction, as shown. The current on the shell is uniformly distributed along the circumference of the shell. side View: cross section view: 21 cylindrical shell (a) [8 pts] What is the magnitude and direction of the magnetic field at point P1 shown above, which is a distance R/2 from the wire? (b) [8 pts] What is the magnitude and direction of the magnetic field at point P2, which is a distance 2!? from the wire? (c) [4 pts] Suppose that a small loop of current is now placed at point P2. This current loop has a magnetic moment with magnitude u, and is arranged so that the magnetic moment points in the +x direction, as shown below. What is the magnitude ofthe torque on this small loop
