Explore magnetic field direction and strength around bar magnets and current-carrying wires using compass arrows whose direction and length show the local field.
Start a free 30-day trial with class codes and progress tracking, or talk to us about your school's licence.
Build and test series and parallel circuits using cells, switches, lamps, resistors, ammeters and wires. Explore complete circuits, current flow, voltage, resistance and…
Complete a guided circuit investigation by building working circuits, testing open switches, comparing one and two cells, reversing cells, measuring current with an…
Explore how electrical devices transfer energy into light, heat, movement, sound and stored chemical energy. Classify useful and other outputs, then complete…
A randomised challenge covering Faraday's Law and Lenz's Law: calculating induced voltage, magnet speed, magnet strength and coil turns, plus reasoning about why a…
An explorer for induced voltage, coils, magnets, and changing magnetic fields — move a magnet through a coil and watch the galvanometer, field lines and electron flow…
A guided investigation that builds up electromagnetic induction step by step: no motion means no voltage, motion induces voltage, and reversing direction reverses the…
Magnetic Field Explorer is one of the licensed interactives in The Education Universe. This page describes it; teachers use it in lessons and classes with a licence or the free trial.
