There are mainly two types of widely used strong magnets– samarium cobalt magnets and neodymium magnets commercially available. If you’ve never handled them before, you will probably be surprised by how powerful these magnets can be. Their magnetic energy product density is more than ten times that of AlNiCo magnets or ferrite magnets. Samarium cobalt magnets and neodymium magnets are exceptionally strong that it is hard to separate the magnets that are attracted together.
There are few ways to separate strong magnets:
For easy separation, we usually add gaskets among the strong magnets. When there turns out gaps among the strong magnets, it comes easier to separate them.
Push the side of the magnet
Instead of pulling the magnets apart directly, it’s much easier to push the strong magnet out from the side and then pull it apart. The more area the magnets are attracted to each other, the stronger the suction is, therefore, when we push from the side, it reduces the area of contact between the two magnets, finally reducing the suction.
Use the edge of the table
The edge of the table is a very good tool. Using the lever principle, most of the strong magnets are placed on the table except the one we want to separate, we can easily push it out. It is important to note that separated magnets must be placed far enough away, so as not to cause damage to magnets or injury to the human body.
