Cyclotron Experiment Visualizes Bent EMF field light in Vacuum
This is an Electro Magnetic Field in a Cyclotron showing that in fact Magnets are by nature curving fields.
"Beam of electrons moving in a circle, due to the presence of a magnetic field. Purple light is emitted along the electron path, due to the electrons colliding with gas molecules in the bulb. A Teltron tube is used in this example."
