(A) The current of 1.65 A is flowing via a 1675 turn solenoid of length L = 31.7 cm. Determine the magnitude of the magnetic field within the solenoid?
(B) A Helmholtz coil is employed to produce a uniform magnetic field. Assume that the Helmholtz coil includes of two sets of coaxial wire loops with 15.0 turns of radius R = 79.1 cm, which are separated by R, and each and every coil carries a current of 0.131 A flowing in the similar direction. Compute the magnitude and direction of magnetic field in the center among the coils.
