Below are sample questions representative of the exercises included on this worksheet and related 4.33 Electromagnets (Introductory) skill assessments:

Problem 1Difficulty: Mastery

At a STEM station, a group must build the strongest electromagnet that is still safe. They can choose ONE change. The materials are the same iron core and insulated wire. Which choice is best if the goal is strong magnetism but lower overheating risk?. Use the setup evidence to support your answer.

AIncrease current a lot and keep the circuit on continuously.

BAdd more coil turns and use a switch to run short, repeated trials.

CRemove the iron core and increase the current to compensate.

DUse bare wire so the circuit has no resistance.

Solution & Explanation:Adding turns boosts strength without needing a large current increase. A switch and short trials limit heat. Continuous high current, bare wire, or removing the core is unsafe or weaker.

Problem 2Difficulty: Mastery

At a STEM station, a student tests four designs and records how many washers each electromagnet lifts after 5 seconds. All use the same iron core and insulated wire. Data:,,Science - Design A: 30 turns, 1 battery → 9 washers,Science - Design B: 60 turns, 1 battery → 15 washers,Science - Design C: 30 turns, 2 batteries in series → 14 washers,Science - Design D: 60 turns, 2 batteries in series → 22 washers,Science "A student wants at least 14 washers but also wants the safest choice (less current). Which design is best?,A. Design A | B. Design D | C. Design C | D. Design B,D. Design B,Designs B

Solution & Explanation:but B uses only 1 battery (lower current) and still reaches 15 washers

Problem 3Difficulty: Mastery

In a class lab, a student tests four designs and records how many washers each electromagnet lifts after 5 seconds. All use the same iron core and insulated wire. Data: - Design A: 30 turns, 1 battery → 9 washers - Design B: 60 turns, 1 battery → 15 washers - Design C: 30 turns, 2 batteries in series → 14 washers - Design D: 60 turns, 2 batteries in series → 22 washers A student wants at least 14 washers but also wants the safest choice (less current). Which design is best? Use the details in this version to choose the best answer.

ADesign A

BDesign C

CDesign B

DDesign D

Solution & Explanation:Designs B, C, and D meet the 14-washer goal, but B uses only 1 battery (lower current) and still reaches 15 washers, making it the safer option.
