Production magnet at home

man first became acquainted with the magnet in ancient times.But very quickly the natural stone has ceased to meet the needs of the people.It was then developed technology for manufacturing magnets.Of course, since then much time has passed.Technology has changed considerably, and it is now possible to produce a magnet at home.You do not need to have special skills and knowledge.It is enough to have on hand all the necessary tools and materials.Thus, manufacturing of the magnet as follows.

magnetic materials

All materials capable of magnetization can be divided into magnetically soft and magnetically.Between them there is a significant difference.For example, magnetic materials retain the magnetic properties for long.

can conduct an experiment: spend some time on a strong magnet iron wedges.As a result, the material will become property of attracting other metal objects.However, the manufacture of the magnet, constantly having these abilities, in this case, impossible.

magnetic materials

Such materials are obtained by conventional magnetizing a piece of iron.In this case, the properties are maintained much longer.However, they disappear completely when hitting the subject of a sufficiently hard surface.Also, magnetic properties are destroyed if the material to be heated 60 degrees.What is needed

Making magnets with their own hands will not take much time and will not require extra costs.This requires:

  • screwdriver;
  • oiled paper;
  • fuse;
  • switch;
  • copper wire;
  • strongest permanent magnet.

first method, this method is considered the easiest.Suffice it to hold in one direction several times magnetizes subject to continual strong magnet.That's all.However, it should be noted that the magnets produced by this method, the magnetic field is kept short and very quickly lose their properties.These products are only suitable for simple manipulation.For example, such a magnet can help remove the rubble from the slot to pull the needle or bolts, but no more.Therefore, this method is not seriously considered.

second method of manufacturing a permanent magnet can be done another way.This will require the battery.You can use it to magnetize any suitable material for this purpose.This is done quite easily and requires no special tools.Magnetic properties of metal objects attached to an electromagnet.

Let's look at an example with a screwdriver.To start the tool should wrap insulator and then wound about 300 turns of wire.It is best to use one that is used for the manufacture of transformers.After that, the wire must be connected to a battery or a battery, preferably 5-12 volts.As a result of such manipulations electromagnetic field magnetize screwdriver.

third way

Making magnet may seem to be difficult.Since the above methods do not guarantee that the property will be kept for a long time.The stronger the magnet can be created using the inductor coil.Metal workpiece should be small, since it must be placed inside the coil.After that you should perform exactly the procedure as described in the previous method.The only difference is that the turns of the wire needs to be done twice, i.e. 600. Only in this way can get good magnet.

fourth method

Making magnet in this case involves the use of electrical current.This method is quite dangerous, so all manipulations should be done carefully and cautiously.We need a fuse, without which nothing happens.It must be connected in series with the inductor coil, which is located inside the metal billet.

Of course, when the construction of such a network fuse blows.However, during this short period of time will have time to recharge metal blank, as in this case, a sufficiently strong magnetic field.There is a caveat worth considering: the higher the current, the stronger the magnet will.For coil winding should be used only copper wire.

In conclusion

Production of permanent magnets in the home - the process is fairly simple.However, the use of certain schemes should observe punctuality.

most powerful neodymium permanent magnets is considered.Produce it at home, you can, but it requires harvesting of rare earth metal - neodymium.In addition, the use of boron, and iron alloy.This preform is magnetized in a magnetic field.It should be noted that this product has great strength and lose only 1 percent of its properties for a hundred years.
