8) Electrostatics
a) Electric Generators
Shows high voltage static charge, electric field, hair
standing on end, and the discharging
effect of point.
-
Van der Graaff Toys
-
Wimshurst Static Generator
Shows high voltage static discharge spark and is used
to power many experiments.
-
White Plastic Golf Rods with Wool for Negative Charge
Used to charge electroscopes, capacitors, plates, etc…
and when used with rotating
spindle to show attraction/repulsion of charges.
-
Clear Plastic Rod with Silk for Positive Charge
Used to charge electroscopes, capacitors, plates, etc…
and when used with rotating
spindle to show attraction/repulsion of charges.
-
Flat Acrylic Plate with Wool and Metal Disk for Induction
Used to charge electroscopes, capacitors, plates, etc…
and when used with rotating
spindle to show attraction/repulsion of charges.
-
Conducting Rod (Also for use with spindle)
b) General
-
Spindle Stand
-
Faraday Cup with Charge Transfer Ball on Non-Conducting Handle
Shows that charge resides on the outside surface of
a conductor using the electroscope
Used to indicate sign and strength of charge. It is
projected on the wall for students to see.
-
Overhead Projection Electroscope
-
Take Apart Capacitor (Leyden Jar)
Charged by Wimshurst generator and can be taken apart
to show where charged is stored.
-
Capacitor Plates on a Stand
Shows a dipole in an electric field (between capacitor
plates). Acts as an electrostatic motor
-
Dipole on Pivot Stand
-
Electrostatic Field Demonstrator for Overhead projector
Shows five different cases of electric fields.
Examples are point change, two point charges, electrostatic
shielding, point charge with
with plate, and two plates.
-
Two Ping-Pong Balls Between Capacitor Plates
Shows repulsion of two like charged balls.
-
Ping-Pong Ball between Capacitor Plates
The ball bounces quickly back and forth transferring
charge between the plates
Shows a fluorescent tube being excited when a static
charge from a acrylic induction
plate is discharged through the tube.
-
Adjustable Square Capacitor with Scale and Dielectric plates
-
Faraday Shielding cages
-
Conducting Spheres On Stands (large and small sets)
-
Electrostatic Chimney Experiment
