Students switch between a single positive charge, a single negative charge, a dipole and like charges, then move a positive test charge through the field to read force direction and field strength. The full interactive is available to licensed Education Universe users.
Ask students to sketch the field lines for a dipole before revealing them.

A guided investigation in which students build a complete circuit, test an open switch, compare one cell against two, investigate opposing cells, measure current with an…
Students explore how electrical devices transfer energy into light, heat, movement, sound and stored chemical energy, classify each output as useful or wasted, and…
Randomised questions covering Faraday's law and Lenz's law, calculating induced voltage from magnet speed, magnet strength and coil turns, and reasoning about why a…
Students move a magnet through a coil and vary magnet strength, speed and coil turns, watching the induced voltage on a galvanometer, the field lines and the electron…
A guided investigation building electromagnetic induction step by step: no motion means no voltage, motion induces a voltage, and reversing the direction of motion…
Electric 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.
