Below are sample questions representative of the exercises included on this worksheet and related 12.122 Electromagnetic Induction skill assessments:

Problem 1Difficulty: Mastery

The table gives two instants for the same loop. The field is perpendicular to the loop. At t = 0, B = 0.30 T and A = 0.40 m². At t = 2 s, B = 0.60 T and A = 0.20 m². What should be concluded?

AThe average emf is nonzero because B changes.

BThe average emf is nonzero because A changes.

CThe flux doubles because the magnetic field doubles.

DNo average emf is induced over the interval because B times A is unchanged.

Solution & Explanation:For perpendicular fields, flux equals B A. The product is 0.12 Wb at both times, so the average flux change over the interval is zero.

Problem 2Difficulty: Mastery

A coil rotates through one complete turn in a uniform magnetic field and returns to its original orientation. What is true during the turn?

ANo emf is induced because the initial and final orientations are identical.

BNo emf is induced because a complete turn cancels all earlier changes instantly.

CEmf is induced during parts of the rotation because flux changes even though the final orientation matches the initial orientation.

DCurrent can appear only at the final orientation.

Solution & Explanation:Induction depends on the instantaneous change of flux during the motion. Returning to the starting orientation later does not prevent emf during the rotation.

Problem 3Difficulty: Mastery

The diagram shows a metal ring near an electromagnet powered by alternating current. Why is induction expected in the ring?

AThe electromagnet transfers electrons directly through the air to the ring.

BThe alternating current changes the electromagnet's field and flux through the ring repeatedly.

CThe ring current appears only if the electromagnet is switched to steady direct current.

DNo induction is possible because the ring is not touching the electromagnet.

Solution & Explanation:Alternating current produces a time-varying magnetic field. If that changing field passes through the ring, the changing flux induces emf and current in the closed ring.
