A cylindrical conductor of radius R = 2.70 cm carries a currentof I = 3.30 A along its length. This current is uniformlydistributed throughout the cross section of the conductor.
(a) Calculate the magnitude of the magnetic field midway along theradius of the wire (that is, at r = R/2).
Round your answer to three significant figures. Take thepermeability of free space to be 4Ï x 10^(-7) T*m/A.
____________ μT
(b) Find the distance beyond the surface of the conductor at whichthe magnitude of the magnetic field has the same value as themagnitude of the field at r = R/2.
____________cm
