In the video clip below, the gas in the tube glows blue along the path followed by electrons.

Exercise 2

In your journal describe the path of the electron. Record in your journal why the electron moves along that path. For example, why does it curve the way it does?

What direction is the magnetic force on the electron?

Remember that electrons are negatively charged (q = -e).

In what direction does the magnetic field point?

Go to Hall Effect.
