Question

A circular loop of radius 11.9 cm is placed in a uniform magnetic field.

A circular loop of radius 11.9 cm is placed in a uniform magnetic field. If the field is directed perpendicular to the plane of the loop and the magnetic flux through the loop is7.60 times 10-3 T m2, what is the strength of the magnetic field? Your response differs significantly from the correct answer. Rework your solution from the beginning and check each step carefully. T If the magnetic field is directed parallel to the plane of the loop, what is the magnetic flux through the loop?

Explanation / Answer

a.)when magnetic field is perpendicular to the plane of the loop,

flux=BAcos(theta)

theta=0

7.6x10^-3=B.pi*0.119^2

So B=0.171 T

b.)when magnetic field is parallel to the plane of the loop,

theta=90

So flux=BAcos(theta)=0
