What does ferrofluid do?

Marvel at the behaviour of the CHE 006 ferrofluid. It clings to magnetic items, can be moved around with magnets and can be used to make unusual patterns with magnetic fields. Ferrofluid is made up of many micron-sized magnetic particles called magnetite with mineral oil. The particles are coated with a surfactant to stop them from clumping together allowing the fluid to move easily.

What does this teach?

Demonstrate magnetic fields and magnetism. The ferrofluid is a great way of demonstrating how electromagnets work, magnetic fields and attraction. A rare earth magnet is also included in the kit.

Another experiment is to show an apparent density change as a magnet is applied. Without a magnet a penny will sink in the fluid but with a magnet placed under the fluid the penny rises to the surface.

Ferrofluid can be very messy and can stain so should be used with adult supervision and in protective clothing eg. Gloves and disposable aprons.

Rated 5 out of 5 by from excellent sticky-stuff! I purchased the ferro magnetic fluid about 7 weeks ago, fascinating stuff! But don't get on your clothes!!

can this product be used in audio speaker applications - more specifically the dampening of tweeter voice coils? If not can you recommend anywhere in the uk that sells this for a reasonable price? Regards Glenn
