Every magnet has a positive and a negative so you can use and old speaker magnet.
The best and most strongest magnet to do this with is use an old hard drive magnet, they are so darn strong it is unreal.
So the more powerful the magnet then the more powerful the screwdrivers will become.
This however is really good and better than I thought and does a real good job of magnetising my screwdrivers.
Obviously I do not want all my screwdrivers to be magnetised especially the ones for watch repairs and computer repairs.
The size is 50mm x 50mm x 28mm and is an ideal size for any thickness of screwdriver. It is stronger than I thought and will magnetise the screwdriver enough to pick up larger type scews but stick the smaller type as you don't need them for the larger screws.
I received the red one and is identical to the one pictured.
For the price I would by one and I certainly would ignore the silly reviews and all the bad ones as there is nothing at all wrong with this little devise.
Just for your information, this is about the size of a British 3 pin plug without the pins of course :-)
