Homework Statement
Along a circular path the magnetic field is measured and is found to be uniform in magnitude and always tangent to the circular path.
If the radius of the path is 0.03 m and B along the path is 1.4e-06 T, use Ampere's law to calculate the magnitude of the conventional current enclosed by the path.
Homework Equations
