PROF BUNSEN (EM) - LENZ'S LAW TUBE
This is one of our favourite demos in the physics classroom! As the powerful neodymium magnet is dropped through the aluminium tube, eddy currents are generated in the tube and these oppose the movement of the magnet. The resultant force slows the magnet down so it falls at constant speed taking 10 seconds to emerge. Included: One thick walled aluminium tube, a neodymium magnet and instructions. Age: 10+ Code: PBSE03. Suppliers to schools & laboratories of science equipment & laboratory grade chemicals.

PROF BUNSEN (EM) - MAGNA BALLS
Some call it Buckyballs(TM), the NeoCube(TM) or NanoDots(TM). We simply call it Magna Balls as each 5 mm ball contains A powerful rare-earth neodymium magnet. And they are all pulling their weight as each tiny ball can easily uphold 225 grams! IN THREE COLOURS - NICKEL, BLACK OR BLUE. This amazing magnet craze has been labeled the New Rubik's Cube. This is not A toy for children - rather an amazing adult desk top scientific novelty that is simply irresistible. Snap, pull, tear, mould, squeeze and construct an endless variety of shapes with the 216 balls included. Make sculptures, puzzles, patterns, stick stuff to the fridge or play A game of fridge 'darts'! Included: 216 neodymium magnet balls of 5 mm diameter each. Supplied in A plastic bag. Plus A free pouch to keep your magnets safe. WARNING: This product in not intended for children below the age of 14 years. Swallowed magnets can stick together across intestines causing serious infections and death. Always seek immediate medical attention if magnet(s) are swallowed or inhaled. Age: 14+ Not A toy! By purchasing this product the buyer acknowledges that he/she is aware that 1. this is not A toy for children and 2. that the ingestion of magnets can be extremely hazardous. Note: The colour of the blue Magna Balls are slightly darker and more metallic than depicted Code: PBSE31. Suppliers to schools & laboratories of science equipment & laboratory grade chemicals.

PROF BUNSEN (EM) - MAGNET ACCELERATOR
This could be the most amazing science demo of the decade! A plastic channel supports two neodymium magnets each associated with three steel balls. Now - roll the loose ball slowly towards the first group. As it approaches the magnet, it accelerates and amazingly shoots off the steel ball at the other end at A high speed! This ball activates the second group and the end ball flies off at A fantastic speed. Yes - this is known as A Gaussian rail gun too! Watch as students try to figure this out and then experiment with other combinations . . . three balls and A magnet, four balls and two magnets . . . Included: Steel balls (7), neodymium magnets (2), channel track (1), Prof Bunsens notes Age: 9+ Code: PBSE14. Suppliers to schools & laboratories of science equipment & laboratory grade chemicals.
