A copper ring is oriented perpendicular to a uniform magnetic field. IF the ring is quickly moved in the direction opposit ( anti-parallel) to the magnetic field line, how will the magnitude of the net magnetic field in the center of the loop compare to the magnitude of the uniform field? Note that the net magnetic field in the center of the loop will equal the loop will equal the uniform field plus any induced magnetic field.
A. The net field will be greater than the uniform field.
B. The net field will be equal to the uniform field.
C. the net field will be less than the uniform field
D. there is no enough information to detrmin this
WHy?
