live techno – How to make your own magnet can be done with simple tools and maybe you can find at home. This article will specifically discuss how to easily make magnets for school work.

However, before discussing how to make a magnet, it helps us to know the properties of magnets in advance so that the understanding of magnetism can be better understood.

The book Basic Physics, Series: Direct Current Electricity and Magnetism cited by Sisavanto et al. A magnet has two opposite poles, namely the North Pole and the South Pole. If the magnet is cut into smaller pieces, the north and south poles will remain.

1. Not all objects can be attracted by a magnet, so a magnet can attract only some objects around it.

2. The magnet has a force that can penetrate objects, that is, if the magnetic force is high then the magnetic force can penetrate thick objects.

3. If there are two magnets having different poles, and they are brought close to each other, they will attract each other.

4. When poles of the same type are brought near each other, they repel each other

5. The magnetic field will create a magnetic force, which when an object is brought closer to a magnet, will have greater magnetic force produced by the magnet and vice versa.

6. If a magnet is constantly dropped and burned, the magnetic properties may be reduced and even lost.

According to the book Easy to Master Physics for Junior High School Class 3 compiled by the editor of Kavan Books, there are two types of magnets, namely natural magnets and artificial magnets. Natural magnets are formed naturally without human intervention, such as earth magnets and magnesian stones.

Meanwhile, artificial magnets are magnets intentionally created by humans from pure steel or iron. This type of magnet can also be made of alloying materials such as steel alloyed with nickel or an alloy between aluminium, cobalt and nickel.

Well, here is an easy way to make magnets that you can try at home or at school

1. How to Make a Magnet With Electromagnetics

Electromagnetic induction is the principle that an electric current can generate a magnetic field, and a magnetic field can generate an electric current. reported from live scienceIf current flows through a coiled wire, a magnetic field will be generated around it according to the right hand rule.

The easiest way to make an electromagnet is with a battery, steel nails, tape, and wire. Wrap the steel nail in a circle with wire, then attach the wire to the ends of the battery and cover it with tape.

If you have, the nail wrapped around it will conduct electric current so that the nail will turn into a magnet and can attract other objects according to the nature of the magnet.

2. How to make a magnet by rubbing

Another way to make a magnet is to rub a permanent magnet on a ferromagnetic object repeatedly and in the same direction.

Ferromagnetic substances are those materials that have a permanent magnetic moment so that they can be attracted by a magnet. Examples of ferromagnetic materials are iron, cobalt, nickel and steel.

To make this you can hold a permanent magnet and rub the surface of the magnet on the iron rod. Do this for about 3 to 5 minutes.

Then bring the iron which has been rubbed with a needle or any such object which can be attracted by a magnet, if the needle can be pulled then it means that the iron has become magnetic.

3. How to make a magnet by induction

Magnetic induction is the approach of a ferromagnetic material (iron, cobalt, nickel, or steel) with a permanent magnet without the need for contact. The permanent magnetic field will align the magnetic moments in the iron so that the iron becomes a magnet.
