Below are sample questions representative of the exercises included on this worksheet and related 12.120 Magnetic Force on Current Carrying Wires skill assessments:

Problem 1Difficulty: Mastery

A loudspeaker coil has fixed length in the magnetic field and fixed field strength. Which change would double the peak magnetic force on the coil?

ADouble the audio frequency only.

BRotate the wire parallel to the field.

CDouble the peak current.

DReverse the current without changing its size.

Solution & Explanation:For fixed L, B, and angle, peak force is proportional to peak current. Doubling peak current doubles peak force.

Problem 2Difficulty: Mastery

A diagram shows a rectangular current loop in a uniform field at an instant when the side forces form a clockwise couple. What are the net translational force and rotational effect?

AClockwise net force with zero torque

BZero net force with clockwise torque

CZero net force with zero torque

DUpward net force with counterclockwise torque

Solution & Explanation:In a uniform field, forces on opposite sides cancel as vectors for translation. Because the equal and opposite forces act at different locations, they can form the clockwise torque shown.

Problem 3Difficulty: Mastery

An audio signal sends a 440 Hz alternating current through a speaker voice coil in a fixed magnetic field. Ignoring mechanical details, what is the frequency of the magnetic force oscillation?

A220 Hz

B880 Hz

C440 Hz

D0 Hz

Solution & Explanation:The magnetic force is proportional to the signed current, so it completes one full push-pull cycle for each current cycle.
