5H Magnetic Fields & Forces

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.

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.

Levitation Using Permanent Magnets

The many parts to the Levitron demo are shown here.
Catalog: 
5H20.20C
Location: 
Cc4
A spinning magnet made by Levitron levitates over a permanent magnet.

Field of a Toroid

Iron filings clearly show students the magnetic field created by a toroid.
Catalog: 
5H15.50
Location: 
Cc3
Iron filings show the field of a toroid which is wound through a sheet of Plexiglas.

Robby the Seal

The seal can either balance the ball on its nose or when it approaches the ball
Catalog: 
5H20.121B
Location: 
Cd3
Robby the Seal can balance the ball on his nose or when he approaches the ball it begins to spin.

2-D magnetic field viewer

Catalog: 
5H10.301A
Location: 
Cc2
Consist of an array of loosely confined metal pins in a clear plastic case. To be used in conjunctions with a overhead projector

Magnet & Iron Filings - Video

Catalog: 
5H10.30C
Location: 
3_1
Cinema Classics: Magnetism & Magnetic Fields: Iron Filings. Iron filings are sprinkled over a horseshoe magnet and bar magnet to show field lines. A compass is moved around the bar magnet. An 83 ton electromagnet is shown. Students throw iron bars on it. Helicopter view of students lining up along field lines with the help of compasses.

Forces on an Electron Beam - e/m - Video

Catalog: 
5H30.21B
Location: 
3-1
Cinema Classics: Electromagnetism: Electrons in a Magnetic Field. Helmholtz coils around a cathode ray tube deflect electron beam through rarified hydrogen gas. Beam makes a complete circle. Parameters are measured so the charge to mass ratio of the electron can be calculated.

Right hand rule

The stand can hold the vector in many positions.
