Large neodymium magnets are notable for their tremendous adhesion to metal and do not demagnetize over time. What to do if two magnets are connected? How to disconnect neodymium magnets at home using conventional home tools?
To disengage the magnets, use only wooden wedges that are inserted between the two magnets. You may need to take a hammer or any other percussion instrument. With light strokes, a wedge is hammered between two neodymium magnets. As the wedge goes deep, traction decreases. After a while, the magnets can be unfastened by hands and not be injured.
Use of wedges is justified if the magnets are small. But how to disconnect neodymium magnets, the adhesion force of which is 180 kg or more? You can use the improvised "guillotine" from a desk, dresser or door.
The basis of this method is the simple principle of cutting one of the magnets. The jamb of the door, frame of a chest of drawers or a table will lie as a supporting fixed part. As a sliding mechanism, you can use drawers, a door. It is worth considering that not all furniture and interior items are suitable for the tasks of separating magnets - only high-quality chipboard assemblies or wooden doors made of natural wood can withstand such loads.
Using the wooden guillotine
Separate neodymium magnets can be another way. One of the magnets must be placed in a suitable hole in the wall. The other magnet is shifted with the long lever to the side - this way you will be able to separate two strong magnets from rare earth materials. This method is relevant for small products, but if you need to unscrew the search magnets, then this method will not work - you can’t always find a suitable hole in the walls.
Using your own efforts
A neodymium magnet with with a capacity of 150 kg or more, you can tear it from a metal or from another magnet without any adaptations - you only need your own forces. How to disconnect neodymium magnets at home or in any other environment without tools is described below.
To solve the problem, you need to install magnets on a flat surface - it can be, for example, a table. It is important to place the details so that the connection line runs along the edge of the table or bedside table. One point should be noted: one of the magnets should lie on the surface, and the second should hang from it.
To disconnect, hold the object lying on the table with one hand, and the hanging element is firmly clamped. To breakdown will require maximum effort. The force vector is directed vertically - the force is directed perpendicular to the plane of the table or the surface on which the magnet lies. After you manage to unfasten the two connected elements, one of them needs to be put aside no less than a meter from the other.
Here's how to disconnect neodymium magnets using human capabilities. If the first time it didn’t work out or you don’t have enough strength to breakdown, then it’s better to use one of the methods described above.
If a magnet sticks to a metal surface
Sometimes a powerful rare-earth neodymium magnet sticks to various metal surfaces. It can be an entrance door, a sewer hatch, a car body. If this is a powerful search magnet, then to disconnect you will have to make a lot of effort or use improvised devices. How to disconnect neodymium magnets at home or unfasten a magnet from a metal surface? The following method is proposed.
If the surface is even and fairly smooth, then the easiest option is to move the magnet to the edge of the sheet of metal. If this method is not effective, then it will be safer and safer to use wooden wedges.
