Title
J3-01: EXISTENCE OF ELECTRIC FIELDS
Demonstrate the existence of electric fields and to map them semi-quantitatively.
J3-02: ELECTRIC FIELD OF RING OF CHARGE - MODEL
Aid in the visualization of the electric field of a ring of charge
J3-04: ELECTRIC FIELD LINES - SOAP BUBBLES
Show the shape of electric field lines for a large dipole by observing soap bubbles move along the lines.
J3-05: VAN DE GRAAFF - INDUCTION WITH SPHERES AND NEON BULB
Demonstrate the existence of electric fields and to identify the polarity of the charge on a sphere.
J3-06 ELLIPSOIDAL CONDUCTOR
Demonstrates that charge distribution on a conductor depends on the surface curvature
J3-07: VAN DE GRAAFF - DISCHARGE TO VARIOUS RADII
Demonstrate that for a charged conductor a smaller radius produces a higher electric field.
J3-08 VAN DE GRAAFFS - INTERACTING FIELDS
Shows field lines for two identical charges
J3-11: EQUIPOTENTIALS/LINES OF FORCE - ONE CHARGE
Aid in visualization of equipotentials and lines of force.
J3-13 POTENTIAL SURFACE MODEL WITH E FIELD VECTORS
Illustrates the relationship between the electrostatic potential and the electric field
J3-14 FLUX MODEL - ELECTROSTATICS
Aid in visualizing flux at an angle through a surface
J3-21 FARADAY CAGE
Demonstrates that the electric field within a closed conducting surface is zero
J3-22: FARADAY CAGE - ELECTROSCOPE
Demonstrate that the electric field within a closed surface is zero.
J3-23 FARADAY CAGE - RADIOWAVES
Demonstrates that radio waves cannot penetrate a Faraday cage
J3-24 HOLLOW CONDUCTING SPHERE
Demonstrates that charge resides on the outside surface of a conductor
