Great Magnetizer/OK Demagnetizer,
By
Amazon Verified Purchase(What's this?)
This review is from: Wiha Tools Magnetizer/Demagnetizer (Tools & Home Improvement)
This is a simple, inexpensive device that really works well, within limitations. The magnetizer works great. Slowly inserting a tool (made of a metal capable of being magnetized) into the + chamber and then slowly retracting it readily magnetizes it. Works great when you want screwdrivers to grab onto screws.
Demagnetizing a tool, however, is more difficult. To thoroughly demagnetize a tool, you probably need an electromagnetic degaussing coil. This much simpler device is OK, but a bit tricky to use. As others have noted, there are no instructions included. The - chamber has a series of steps, and it's not obvious what their purpose is. I contacted Wiha tech support, and they responded promptly (two service reps sent e-mail). Below are their instructions. It is important to note that the tool tip can be so strongly magnetic that the screw or other part it touches can itself become magnetized. So to test the demagnetizer, you need to test the demagnetized tip on a fresh (previously unmagnetized) part; otherwise, if the part itself is magnetized, you would incorrectly conclude that the demagnetizer didn't work. From Wiha tech support: "You put the screwdriver blade slowly in and out of the + side to magnetize and slowly in and out of the - side to demagnetize. If you are having trouble demagnetizing put the blade in slowly at the top of the demagnetizing side, walk it down the steps and then remove. Magnetism transfers so you need to be careful to not keep magnetized and demagnetized items together. Parts under 1" in length or 1/8" diameter may not demagnetize. (Do not use a paper clip to check if a tool is demagnetized, because of the size once it is magnetized it cannot be demagnetized and transfers the magnetism back to the other tool.) Also if you are trying to demag an item with larger mass it will take repeated attempts to demag it."

Great gadget,

This review is from: Wiha Tools Magnetizer/Demagnetizer (Tools & Home Improvement)
This is a great gadget to have in the field or at your bench. It is very compact and super simple to use. I got it because I frequently work with teeny (0 & 00) screws and having a magnetized driver makes life so much easier. It is also wonderful with #2 and #3 bits if you're working in a cramped space and don't have enough hands to hold the fastener, the tool, and the item you're trying to install.

This magnitizer is not a toy. It magnitizes my screw drivers so I can pick up metal screws. Excellent bargain.
