Watch a magnetic field split a single spectral line.

Students see a magnetic field split a spectral line and measure the splitting themselves.

Try it yourself

Turn up the magnetic field

Drag the field strength and watch the red cadmium line split into three components, just as students see it through the optics.

What your students will do
1

Light the lamp in the field

A spectral lamp sits between the poles of the electromagnet, with the field strength under the student's control.

2

Resolve the spectral line

High-resolution optics separate the fine structure so the splitting becomes visible.

3

Measure the splitting

Increase the field, record how far the components separate, and connect the result to the Bohr magneton.

Common questions
Does it work on U.S. power?

Yes. Units supplied through American Scientific are adapted for 110V/60Hz and supported in the U.S., including warranty and replacement parts.

What else do I need to run the experiment?

Tell us about your lab in the form above and we'll put together a complete, ready-to-teach configuration, so nothing is missing on day one.

Can grant funding cover this?

Often, yes. Many institutions fund PHYWE equipment through NSF, Title IV and CTE programs, and our team can help you find and apply for the right opportunity.
