Mit Physics Demo -- Faraday's Cage

In the electric field of a Van de Graaff generator, an unprotected Ben Franklin feels electrostatic forces. However, when a metal cage surrounds him, he is completely shielded against any electricity or electrostatic force. This is due to the fact that all charges in a conductor reside on the outer surface, and always rearrange themselves to cancel out the electric field in the interior.

Mit Physics Demo -- Adjustable Capacitor With Dielectric

First, an adjustable parallel-plate capacitor is held at a constant voltage. As the separation between the plates is widened, the electrometer shows charge (or current) flowing off of the plates, while the electroscope shows no change in voltage. Notice (by the deflection of the needle) that more charge flows off of the plates when they are closer together, and less when further apart. When the plates are brought back together, we see charge flowing back onto of the plates. Next, ...

Mit Physics Demo -- Balloons In Liquid Nitrogen

This demonstrates the ideal gas law (PV=nRT) which states that a drop in temperature with fixed mass and external pressure will result in a smaller volume, and vice versa. See the original video and more on MIT TechTV here - techtv.mit.edu/videos/1712-balloons-in-liquid-nitrogen

Mit Physics Demo -- Dissectible Capacitor

Leyden Jars, an early style of capacitor, can be connected to the two electrodes of the Wimshurst Machine. They will store charge as it is generated, giving a much stronger spark across the gap. Next we have a three-piece dissectible Leyden Jar consisting of two metal cups separated by a glass cup. When charged with the Wimshurst machine, we see by touching it with the shorting rod that it holds a large amount of charge. However, when disassembled, the metal ...

Mit Physics Demo -- Temperature Effect On Resistance

A light bulb is connected in series with a coil of very fine copper wire and a DC power supply. The voltage is adjusted so that the bulb glows dimly. When the coil is immersed in liquid nitrogen the resistance of the wire decreases causing the current to increase and the bulb to glow brightly.

Mit Physics Demo -- Inducing Dipoles With A Van De Graaff Generator

First, a dipole consisting of two conducting balls connected by an insulating rod swings at the end of a long plexiglass rod. The two balls are charged oppositely by touching it to a conducting rod in the field of a Van de Graaff generator. The generator is negatively charged, which induces a positive charge on the closer silver ball, and a negative charge on the further gray ball. Going around the generator, the dipole always aligns itself with the electric ...

Mit Physics Demo -- Confetti And The Van De Graaff Generator

Paper confetti is placed atop a (en.wikipedia.org/wiki/Van_de_Graaff_generator) Van de Graaff generator and flies off when the grounding rod is removed. When turned on, a Van de Graaff generator builds up lots of negative charge on its large metal sphere. A grounding rod is used to protect the demonstrator and control the amount of charge. When the paper confetti is place on the sphere the charge jumps onto it, but since paper is an ...
