Then Jean-Baptiste Perrin conducted a very simple but very
clever experiment. He accelerated a beam of electrons in a glass
tube. You can see at the start of my video how the spot on the
glass tube is the impact of the electrons causing fluorescent on
paint on the inside of the tube. He then setup a magnetic field
at 90 degrees to the beam using coils of wire (Helmholz coils).
As you increase the current flow inside the coils the field
becomes stronger causing the beam to curve according to Flemings
LH rule of FBI. Now as the bea
