Whether it is assembling small-scale items such as clocks or working overhead, if the screws or small items do not hang properly or overly on the tools, then the frustration becomes great. With a magnetizer & demagnetizer from our online shop, this cannot happen to you anymore!
Why do you have to magnetize or demagnetize tools at all?
Tools such as screwdrivers or tweezers are not naturally charged magnetically. But when it comes to working in hard-to-reach places or overhead with just those work tools, a magnetizer or demagnetizer can be the savior in distress: the smaller the screw, the harder it is to place it properly. However, if the screwdriver is magnetized, the screw simply sticks to the tip.
However, the whole thing works the other way around too: For example, when working on a clockwork or other precision mechanical devices, it is problematic when tools are magnetically charged. Adhesive forces can easily lead to disruptions of the mechanism. Here the demagnetizer helps. This allows all residual magnetism to be removed in a few seconds.
The demagnetizer uses the magnetic force
The magnetizing and demagnetizing device makes use of the rules of physics. More specifically the properties of magnets. The demagnetization purely physically describes the loss of magnetic polarization of permanent magnets or ferromagnetic materials. Magnetization is then charging with magnetic force of substances.
A demagnetizer uses two permanent magnets and their magnetic fields. These are arranged so that the respective same poles lie directly above each other. This creates a repulsive magnetic force. The field strength varies alternately. Now, when a ferromagnetic object is introduced into this arrangement, the elementary magnets are arranged therein to be demagnetized or magnetized.
How does the demagnetization of tools work?
With our demagnetizer, magnetic loading and unloading of tools such as screwdrivers or tweezers is an easy play:
- Magnetize: Slowly guide the item through the + opening of the device. If necessary, repeat up to three times.
- Demagnetize: Guide the tool through the - opening just as slowly.
Depending on the nature of the screwdriver or tweezers, you must use the different steps. This can best be found out by trying out.
Important: Before you pass a tool through the demagnetizer, you must charge it magnetically. Otherwise, the process will only work conditionally.
With our pocket size demagnetizer, you always have the right tool in the drawer. In addition, you will find in our online shop even more practical helpers for everyday work, such as magnetic bowls, magnetic clipboards or magnetic rods.
This affects the magnetization or demagnetization
In large-scale industry, just like home improvement, this magnetic force can be created and then selectively used or switched off. The demagnetizer is also subject to the general rules and factors of magnetism. Magnetic forces are determined by these influences:
- Direction of movement: Depending on how an object is pulled through the magnetic field, the effects on the material change.
- Frequency of the magnetic field: The thicker an object, the stronger the field must be.
- Magnetic field strength: This depends on the hardness of the material to be treated with the demagnetizer. The harder the matter, the stronger the magnetic field has to be.
- Passing speed: This can be decisive, especially for large and heavy objects. Often several runs are needed.
- Shielding: Especially in industry, products are often stored in transport baskets. However, these impede the demagnetizer because they can shield the magnetic fields of the objects.
