About this app
How Electric Motors Work is an interactive science simulation for exploring current, magnetic fields, force, and motor rotation. Learners move a compass around a magnet, reverse current and field directions, and operate a commutator to see why a coil keeps spinning in one direction.
Use cases
- Middle school science students studying electromagnetism
- Teachers demonstrating magnetic fields and motor principles
- Learners practicing the relationship between current, field, and force
- Classroom activities on commutators and electric motors
Features
- Four compass positions for reading magnetic-field direction
- Controls for reversing wire current and magnetic-field directions
- Visual demonstration of the force on a current-carrying wire
- Commutator on/off control for a rotating square coil
- Push-to-spin interaction showing continuous rotation or juddering and stopping
- Step-by-step missions with reset and next controls
