Delivered material: You will receive 1 piece of magnetizer/demagnetizer. The magnetiser has the dimensions 33 mm (length) x 28 mm (width) x 16 mm (depth). Magnetization of metallic objects: The magnetizer can be used to magnetize or demagnetize screwdrivers, tool tips, tweezers as well as bits, other smaller metallic objects and small ferrous tools. Easy to use: The Magnetastico magnetizing device is extremely easy to use. The magnetisation of tools, e.g. a screwdriver, is simply & quickly: Just move the tool up & down in the opening in the middle of the magnetiser. To demagnetise the tool tip, move it analogously in one of the semicircular recesses on the side. It may happen that a residual magnetic force can still be felt after demagnetization, but it will decrease over time!
