Question

A flat, circular loop has 15 turns. The radius of the loop is 14.0 cm and the current through the wire is 0.55 A. Determine the magnitude of the magnetic field at the center of the loop (in T). T

Answer 1

0.000037007 T

Step-by-step explanation:

Current in the loop I = 0.55 A

Radius of the loop = 14.0cm = 0.14m

Number of turns in coil = 15turns

B = μ• nI/2R

= 4π×10^-7T.m/A × 15× 0.55/2(0.14)

= 0.000001256×15×0.55/0.28

= 0.000010362/0.28

B = 0.000037007 T
