5 Electricity & Magnetism

Conductors vs Insulators

A "pith" ball may be used in place of an electroscope
Catalog: 
5A30.15A
Location: 
Attach an electroscope to one end of a metal rod. Bring a charged rod near the opposite end and the electroscope will deflect showing that charges will move through a conductor. Replace the metal rod with an acrylic one and the electroscope will not deflect when a charged rod is brought near the opposite end. A "pith" ball may be used instead of the electroscope.

Generator Driven by Falling Weight

Generator Driven by Falling Weight
Catalog: 
5K40.85A
Location: 
Da4
A falling 2kg mass driving a generator, falls slower when the generator is under the load of a lightbulb.

Gauss Accelerator "Gauss Rifle"

Catalog: 
5G10.55
Location: 
Cb4
A Gauss accelerator made from spherical magnets and ball bearings.

Hand Held Tesla Coil & Lamps

Catalog: 
5N20.25
Location: 
Dc2
Hold a hand held tesla coil near a fluorescent lamp to or use the special socket to turn a ordinary light bulb into a plasma globe.

Magnetic Force Accelerator

Catalog: 
5H40.31
Location: 
Cd1
A current-carrying conductor in a uniform magnetic field experiences a force that is made evident by the conductors rolling along the rails of the apparatus.

Electromagnet with 1.5V Battery

Catalog: 
5G20.70A
Location: 
Cb4
Lift up to 200lbs with only one 1.5V D cell battery for power.

Catalog: 
5K20.10A
Location: 
Cd5
A solid plate pendulum is passed through the gap of a powerful magnet, dramatically demonstrating eddy currents. Then a slotted pendulum is used, with dramatic contrast.

Magnetic Beans

A compass is placed on top of the can while the can is turned.
Catalog: 
5H10.30D
Location: 
Cc2
A can that sits on the shelf for a long time without moving becomes magnetised.

LR time constant on a scope

The stranded core made up of many insulated rods reduces Eddy currents and has t
Catalog: 
5J20.10A
Location: 
Channel A of the oscilloscope is across the signal generator and channel 5 is across the inductor. The waveform varies with the changing time constant.
