Permanent and Temporary Magnets

Let's take a look at what permanent and temporary magnets are. The magnetization property can be permanent or temporary in magnetic material. If the magnetic property of the material disappears when the magnetic field disappears, it is called temporary magnetization. Temporary magnets are used in industry, electric bells, transformer cores, telephone headsets, dynamo and motor armature. Magnets that can maintain their magnetic properties for a long time are called permanent magnets. Permanent magnets are made of cobalt and nickel. These metals can be easily magnetized and retain their magnetic properties for a long time.

Let's continue the topic of permanent and temporary magnets with an experiment. Let's do some operations by taking an iron bar (nail), a steel bar and a magnet. Let's rub your magnet on the iron bar first. The rubbing here will not be like rubbing your two hands together. We rub up and down while rubbing our hands together. When rubbing the magnet on the iron bar, we need to rub it in one direction. It should either just go up or down. This applies to rubbing left and right. When you bring the iron bar, which we rubbed on the magnet, closer to the pins, you will see that it attracts the pins. But after a while your iron bar will not pull the needles. The magnet you created here has been a temporary magnet. When you do the same operations for the steel bar, you will see that the steel bar continues to pull the pins. The magnet you made has become a permanent magnet. The ability of a magnet to be permanent depends on some factors such as the exposure time and ambient conditions. As can be seen, the subject of permanent and temporary magnets is an interesting and intriguing subject. Magnetic materials magnetized by friction lose their magnetism in the face of factors such as hammering and heating. This result proves that the arrangement of the atoms that make up the matter is effective in the magnetization of the matter. When the magnet splits, each piece retains its magnetic property. You can get smaller magnets by dividing the magnet you have divided into two again. Let's look at what is irregularity in permanent and temporary magnets. In the non-magnetic iron and steel bar, the magnetic areas are irregular. When these rods are placed in a magnetic field, the irregular regions become regular and gain magnetism.

We hope this article, which gives information about permanent and temporary magnets, has been useful.
