Helmholtz Coils
Two coaxial current loops spaced one radius apart — the classic configuration for a uniform field region. Best viewed in 3D with LIC visualization.
Example scenes
Five curated starting points. Click a card to open the interactive simulator with the scene pre-loaded — or copy the embed code to drop it into a Canvas assignment, a course page, or a lesson plan. No signup required for either flow.
Solenoid with LIC
Long air-core solenoid. Linear Integral Convolution makes the internal near-uniform field and sparse external field visually obvious.
Antiparallel Wires
Two long straight wires carrying equal currents in opposite directions. The textbook-perfect repulsive-interaction pattern.
Bar Magnet Dipole
A single ferrite bar magnet. Iron-filings visualization reveals the classic dipole field pattern from N to S poles.
Cyclotron Motion
A charged particle launched into a uniform magnetic field traces a circular cyclotron orbit — the basis of mass spectrometry.
For teachers: every example is deep-linkable and
embeddable. Share
/try?example=helmholtz in your LMS and
students land in the exact scene with no sign-in required, or paste the
embed code into your course page to drop the simulator in place.
