Mass spectrometer
Accelerate qU=½mv²; in B, semicircle r=mv/(qB); impact distance 2r yields mass from landing point.
Magnetism & inductionB-fields, Ampere force, Faraday/Lenz, and AC basics.

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 “Mass spectrometer” lab practice?
Tune parameters and match readouts to the “Mass spectrometer” 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.
