How Electric Motors Work

by Anonymous

Flip the current and field directions, then toggle the commutator to see why a motor keeps spinning one way.

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
