Below are sample questions representative of the exercises included on this worksheet and related 9.88 Electromagnets skill assessments:

Problem 1Difficulty: Mastery

Which explanation best aligns with the skill focus on current, coils, core material, and applications?

AElectromagnets work mainly because plastic cores create permanent fields.

BElectromagnets work because current in coils creates a controllable field that core material can strengthen for useful devices.

CElectromagnets cannot be used in real devices because their fields cannot be controlled.

DElectromagnets are strongest when no current flows through the coil.

Solution & Explanation:This explanation connects the main causes of electromagnet strength: current in coils produces the field, ferromagnetic cores can strengthen it, and circuit control makes applications possible.

Problem 2Difficulty: Mastery

A team designs an electromagnet to pull a latch closed and then release it. Which test best evaluates the full device function?

AMeasure only the paint color on the latch.

BCount washers once without recording whether the latch releases.

CTest only a permanent magnet that has no switch.

DMeasure both lifting force while energized and release time after the switch opens.

Solution & Explanation:The device must both pull the latch and release it. A good test measures holding or lifting force while current flows and release behavior after current stops.

Problem 3Difficulty: Mastery

Which core choice best fits a temporary lifting magnet that must release nearly all objects when power stops?

ASoft iron, because it magnetizes strongly but does not remain strongly magnetized.

BWood, because it is strongly ferromagnetic.

CAluminum, because it is usually more ferromagnetic than iron.

DHard steel, because it tends to retain magnetism longer.

Solution & Explanation:Soft iron is useful for temporary electromagnets because it strengthens the field while current flows but loses most magnetization when the current stops.
