FAQ
What does MVP mean on this page?
An interactive sketch with formulas and parameters. Polished Ready labs are the full bench experience.
What does the “Direction of Ampere force” lab practice?
Tune parameters and match readouts to the “Direction of Ampere force” relations — useful for prep and demos.
How do I find the Ampere force direction?
Left-hand rule: B into palm, fingers along I, thumb along F.
When is there an induced current?
When flux through a closed loop changes, or a conductor cuts field lines.
