Packagehp.com – Definition, Fields and Forces and Properties of Magnets – You must have seen magnets, or even often use magnets to help with your work. But you definitely only know the shape but don’t know everything about magnets, therefore the admin will review in full about magnets below.
Definition Magnets
A magnet or if it is called a magnet is an object that has a field called a magnetic magnet. It is mandatory for you to know, if the word magnet or magnet comes from a word taken from the Greek language. That is precisely derived from the word magnítis líthos. Meaning itself is a magnetic field.
The magnet itself must have two poles, namely the north pole and also the south pole which is the main characteristic of a magnet, because if it does not have it then it cannot be considered a magnet.
If a magnet with a north pole and a south pole is cut, the magnet will still have a two-pole magnet, namely a north pole and a south pole.
The poles of this magnet itself have unique properties, which if the poles are the same, they will repel each other when brought closer, for example at the south pole and the south pole which are brought closer. Meanwhile, if the two magnets are different, for example, the north and south poles are brought together, they can make the magnets attract each other.
In addition, magnetic poles can also be used to attract objects that contain metal. In addition, if based on their magnetic properties, objects that can be attracted by magnets are grouped into two different types, as below:
1.) Magnetic Objects (Ferromagnetic)
This object is an object that can be attracted by using a fairly large and strong magnet, such as iron, cobalt, nickel and steel.
2.) Non-Magnetic (non-magnetic) objects
The following objects are considered not to have magnetic properties but can be attracted by using a magnet. There are two types of non-magnetic objects, the following is an explanation.
1. Paramagnet
This object is an object that can only be pulled slightly by a strong magnetic force. Examples such as aluminum, copper and platinum.
2. Diamagnetic
Diamagnetic is an object that cannot be attracted by a strong magnet. Examples: mercury, zinc, bismuth and gold.

Magnetic field
So, now that we know what a magnet is, now we’re going to find out what a magnetic field is. When viewed from the science of physics, the magnetic field itself is a field that is formed by the movement that has an electric current charge.
This movement can cause the emergence of a force that is on an electric charge that can give rise to a force that can make other objects move.
Mentioned a magnetic field is a vector field or has a relationship with every point contained in the vector space that can change with time. The direction of a magnetic field is equal to the direction of the compass needle.
As explained above if a magnet has two poles. The two poles are the north pole and the south pole. These two poles can also be expressed using a symbol, namely – and +.
If a magnet with a + pole meets a pole – it will create an attractive force (the poles are different).
However, if a magnet with a pole – meets a pole – or vice versa a magnet with a + pole meets a + pole, there will be a repulsive force (the same pole).
Magnetic Force
What is magnetic force? Magnetic force itself is a force that can occur or be caused by a pull or push that occurs due to the presence of a magnet. Magnets themselves have many types with various forms. Starting from bar magnets, needle magnets, U magnets, cylinder magnets to horseshoe magnets or better known as horseshoe magnets.
Magnetic Properties
Magnets themselves have several properties that are characteristic or main characteristics that are only possessed by magnets, what are the properties of magnets? Here is the review.
- Magnets can be used as directions or compasses.
- Magnets can attract objects that have metallic properties such as iron and so on.
- Magnets have the ability to penetrate objects to exert attraction. The stronger the magnetic force, the stronger the attraction it will exert.
- Magnets have two poles called a north pole and a south pole, besides that the magnetic poles can also be symbolized by – and +.
- If the north pole meets the south pole (different poles) it will provide an attractive force, but if the two poles that are the same as the south pole meet the south pole or vice versa (same poles) there will be a repulsive force.
Thus this review of magnets in full starting from the understanding, magnetic fields, forces and properties. Hopefully the reviews that the admin shares can be useful for those of you who have read this review to the end, that’s all and thank you for visiting.
