Tube Kit and Magnet for Induction and Resonance Experiments

Order code: SC1011
Purchase QTY: (Each)1+    
Scientrific's price  $80.00    
Note: Prices do NOT include GST

Designed and manufactured by and only available from Scientrific.

The kit consists of a 990mm long PVC tube and a 990mm long aluminium tube. The PVC tube's exterior has been painted so that both tubes appear to be made from aluminium. The aluminium tube is the correct size for optimal induced currents.

When the included 22mm 'Super Magnet' is released in the aluminium tube it takes 7 to 10 seconds for the magnet to 'float' down the tube! What do you think happens when the same magnet is released in the PVC tube?

Students have to explain why the magnet acts differently in the non-magnetic and apparently identical tubes.

Possible areas of exploration:
What happens if you drop/float different numbers of magnets down the tubes?
What happens if you introduce spacers between the dropped/floated magnets?

Resonance in a tube:
Another use for the aluminium tube is to strike it on its end for a great resonance demonstration - adjust the resonant frequency by sliding your hand along the tube.

Kit contains:
• 22mm neodymium magnet
• 990mm aluminium tube
• 990mm plastic tube that looks like aluminium
