Description

Present these
demonstrations in front
of your class to excite
your students about learning core physics concepts. Set up and
execution are simple, so you can spend more time
engaging your students. Ideal for introducing a
unit or using as reinforcement after a lesson, these
demos are available for all fundamental physical
science topics.
Observe how an electron beam interacts with a
magnet when each is placed in close proximity
to each other. With this unique demo, a selfcontained
power supply holds a vaccum tube
with an anode and cathode. The cathode end
features a phosphorous coating, which glows
when exposed to electrons. As a student brings a
magnet near, it causes the electron beam to move
in a perpendicular direction to show students
the deflection of an electron and how a cathode
and anode both work. Includes a power supply,
vacuum tube, and instructions. A magent is
required, but not included. Size: 38 x 11 x 6cm. The
tube is 22cm long and has a diameter of 3.7cm.
