I think today’s video will definitely catch your eye. Here’s what you need to make the magic happen: ethyl alcohol, a clear glass bottle, laser printer toner, some iron powder, a rubber-coated block magnet, and 2 rubber-coated disc magnets. As always, these magnets can be found on our website if the wandering magnet caravans haven’t been to your town lately. Ok, let’s get started!
Put some of the iron powder into the bottle, fill the bottle with ethyl alcohol, and then close the lid. Now, we have a bottle of ethyl alcohol with iron powder inside it. Put the bottle on a table to see the liquid inside the bottle is all mixed up.
Then, take out a rubber-coated block magnet and put it at the bottom of the glass.
The iron powder is quickly attracted by the magnet and shows the shape of the magnetic lines.
We can also put a block magnet on each side of the bottle, and move them up and down. As expected, the iron powder is attracted by the magnets and moves up and down.
But what happens if we change the iron powder with toner? Repeat the above steps but use a spoonful of toner instead. Similarly, we can get a bottle of ethyl alcohol with black toner inside it. The liquid inside the bottle is all mixed up.
Now, put 2 disc magnets at the bottom of the bottle. Same as the iron powder, the toner is slowly attracted to the magnets. Put a block magnet on the side of the glass to see what will happen – the toner is attracted again. If you move the magnet, the toner moves with it.
As you’ve probably guessed (or remember from last time), the secret is the magnetic components of the printer toner. The ethyl alcohol holds the toner without dissolving it, allowing it to react to the magnetic fields instead of the static electric charges of your printer.
