← ScienceWhich outcome occurs when a conducting loop is rapidly pulled out of a uniform magnetic field?
A)Induced current opposes the motion✓
B)Loop spontaneously becomes magnetized
C)Magnetic field lines enter the loop
D)No change as field is already uniform
💡 Explanation
When a conducting loop is pulled out of a magnetic field, the changing magnetic flux induces an electromotive force according to Faraday's law, creating an induced current which generates its own magnetic field. Therefore, the induced current opposes the motion according to Lenz's law, rather than magnetization, field lines entering, or unchanged state, which would violate energy conservation and induction principles.
