Question

A solenoid of length 0.250 m and radius 0.0200 m is comprisedof 120 turns of wire. Determine the magnitude of the magnetic fieldat the center of the solenoid when it carries a current of 15.0A.

b. 4.52 ×10–3 T
c. zero tesla
d. 2.26 ×10–3 T
e. 7.50 × 10–3 T A solenoid of length 0.250 m and radius 0.0200 m is comprisedof 120 turns of wire. Determine the magnitude of the magnetic fieldat the center of the solenoid when it carries a current of 15.0A. 4.52 ×10–3 T zero tesla 2.26 ×10–3 T 7.50 × 10–3 T

Explanation / Answer

        B = o NI           =(4*10-7H/m)(120)(15.0 A )           = 2.26× 10–3 T
