Q . A straight section of wire of length L carries a current i. Find the magnetic field associated with this segment at point P, a perpendicular distance D from one end of the wire? Q : Figure shows a cylindrical conductor of radius R which has a current density J = cr n , where c is a constant number. The magnetic fields produced at point R/2 and 2R points are B 1 and B 2 , respectively. If , find the value of n?
