Question

A hollow cylindrical conductor of inner radius a = 9 cm, and outer radius b = 22.5 has a non- uniform current density J = m2 in units of A/m2. b (a) Calculate the magnetic field at distance r = 13.5 cm from the center of the conductor Select one a. 13640.60 E-7 T b. 501.03 E-7 T c. 219.45 E-7 T

Answer 1
