Adjust the voltage between plates and watch how the path of an electron through a cathode ray tube changes.

Test your understanding of charges and electric fields by identifying "hidden" particles.

Shoot an electron at a target, but avoid obstacles by placing positive and negative charges along its path.

Trace the strength and orientation of a magnetic field as you drag a magnet around.
How Electrons Move
Discover the forces affecting the movement of electrons, including electric and magnetic fields.

Being able to control the movement of electrons is fundamental for making all electronic devices work. Discover how electric and magnetic fields can be used to move electrons around. Begin by exploring the relationship between electric forces and charges with vectors. Then, learn about electron fields. Finally, test your knowledge in a fun "Electron Shooting" game!
