Electromagnet Strength Test

One coil lifts more clips. Ask students to predict what will happen. Compare coil with fewer vs more turns briefly. Key idea: Current creates magnetic field; more coil turns can strengthen it. Ask: What can we change to make an electromagnet stronger? Safety and cleanup: Short connections only; wire can warm. https://www.sciencebuddies.org/teacher-resources/lesson-plans/strength-of-electromagnet
