Electric Fields in Matter

Dielectrics in Capacitors

[M | t+ | ★★★] 
Parallel plate capacitor and capacitance meter with insertable dielectrics.
[In-Depth Description]

Temperature Dependance of Permittivity

[S/M | t+ | —]
Liquid dielectrics in parallel plate capacitor are heated to demonstrate temperature effects.

Thermoelectric Effect

[S/M | t+ | —]
Thermocouple junction produces EMF with enough current compliance to energize an electromagnet.
