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 “Charged particle in a uniform B-field” lab practice?
Tune parameters and match readouts to the “Charged particle in a uniform B-field” 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.
