Question

A = 60 B = 70 C = 170 D = 7

6.a. A solenoid of length B cm and radius B/100 cm is comprised of C turns of wire. Determine the
magnitude of the magnetic field at the center of the solenoid when it carries a current of D Amp.
b. A solenoid carries current I as shown in the figure. If the observer could "see" the magnetic field
inside the solenoid, how would it appear?
c. The figure shows a circuit consisting of straight radial lengths and concentric circular
arcs (half circles of radii r and 3r) and it carries the current I. What will be the magnetic
field at the center?
