Magnet full of iron filings
It is fascinating to experiment with magnets (in the picture: THE GIANT) and iron filings.
But anyone who ever tried to remove iron filings (or small splinters of other magnets) from a magnet after the experiments knows that this can be a very tedious task.
I have found a simple solution:
Let candle wax drip onto a piece of paper.
Knead the wax while still warm.
When you press the wax onto the magnet, the filings stick to the wax.
Repeat steps 1 through 3 until all filings are removed.
Finally, you can use a tissue or rag to free the magnet from the wax.
Caution: The hot wax must not be dripped directly onto the magnet since the heat would cause it to lose its magnetic power!
Clean separation: All filings are in the wax, the magnet is blank again.
Addition from the supermagnete team: You can also use adhesive tape to remove iron filings from a magnet.
