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

0.000037007 T

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

as we know our atmosphere or air have different levels. every level has other gasses, and every gas has another permeability. when the light comes from lower permeability to higher permeability, it changes its direction. so that means that when the light comes from the moon to the earth, it changes it's direction many more times. it basically means that the shape of the light part of the moon is changed on the earth.
