How to Make Magnetic Fluid. You can make your own magnetic liquid at home and perform your
own magnetic experiments with a few easily acquired supplies. You will need Copier toner
Graduated beaker Vegetable oil Glass rod Small glass container Rare earth magnet Table Napkins
and cleaning supplies. Ingesting magnetic fluid can be harmful or fatal. Step 1. Pour
1/4 cup of toner into the graduated beaker and then add 2 tablespoons vegetable oil.
Step 2. Stir the mixture with a glass rod until you get a smooth, thin consistency.
Then transfer the mixture to a smaller glass container so it's easier to handle. Step 3.
Test the fluid by placing the magnet against the outside of the container and moving it
over and around the fluid. The liquid will magnetize and follow the magnet around the
container. If the magnetic bond is weak, you need a stronger magnet. Step 4. Try different
experiments. Pour the magnetic fluid onto a table and hold the magnet under the table
to see what happens. Put the magnet directly into a puddle of the magnetic fluid and watch
the fluid occupy the entire magnetic field. Step 5. Invent your own experiments, but make
sure you have plenty of napkins and cleaning supplies -- magnetic fluid can be messy. Did
you know The strongest permanent magnets contain neodymium, a rare earth metal with an atomic
number of 60 and symbol Nd.
