Product description

Magnetic Fluid, also known as Ferro Fluid.

It is a new functional material which having both liquid flow and magnetic properties.

It is a stable colloidal liquid which consists of magnetic solid particles,carrier liquid (also called the media) and surface active agent.

The application

The fluid will not show the magnetic attraction when it is static.

When there is applied magnetic field, The fluid will show the magnetism.

That is why it has been widely used in practice,and have a high academic value in theory.

The Magnetic fluid could be widely used in various harsh conditions like the magnetic fluid sealing, shock absorption, medical equipment, sound adjustment, light displays, magnetic fluid mineral processing and other fields.
