I have always wondered how the inexpensive magnetizer-demagnetizer tool works. What's inside it? And why are there stairs inside the demagnetizer opening?
According to most sources the stairs are important, but the explanations are vague at best.
In this video, I will do some investigation and open the tool to finally figure out how it really works! And show how you don't need the tool if you have a bar magnet...
