What is a ferromagnetic fluid we hear you ask? The short answer is that it’s a great way to visually see the invisible magnetic fields that are all around is in our everyday lives! Ferromagnetic fields or magnetic liquids contain nanoscale particles of a magnetic substance inside of a liquid. When a magnet comes close by, the tiny particles align to the magnetic fields. This ferromagnetic fluid kit allows kids (or adults, scientific inquiry has no upper age limit!) to make their own ferrofluid and experiment with it.
The ferromagnetic fluid kit contains a packet of magnetic nanoparticles, plus a magnet and a test tube. To make the fluid, simply add the packet to the test tube with some water. Put the top on and you’re ready to see the ferromagnets in action! The miniscule magnets dance around in the fluid and follow wherever the magnet goes! Drag them up and down the tube or get the magnet up close, then watch what happens as you pull it away – it’s mesmerising!
This kit is intended for kids ages 14+. Keep out of the reach of younger children and pets. Children should always be under supervision around magnets since they can cause injury if swallowed.
The ferromagnetic fluid kit is a fascinating gift for kids with curious minds and makes an excellent choice for a birthday or Christmas present for your older grandkids, nephews and nieces!
