Properties of artificial magnets
Answers
Answer:
The poles are the two points near but within the ends of the magnetic materials, at which the entire magnetism can be assumed to be concentrated. The poles always occur in pairs and they are of equal strength. Like poles repel each other and unlike poles attract each other.

Answer:
A magnet that is prepared artificially form the artificial magnets. Examples include an electromagnet, a magnetic needle, horseshoe and bar magnets etc. According to the molecular theory, every molecule of a magnetic substance, irrespective of whether or not it is magnetized.
The poles are the two points near but within the ends of the magnetic materials, at which the entire magnetism can be assumed to be concentrated. The poles always occur in pairs and they are of equal strength. Like poles repel each other and unlike poles attract each other. This is all the basic information about magnets. Now, we will look deeper into the properties of magnets.
Magnets attract magnetic substances like steel, cobalt, iron etc. This is also known as its attractive property.
When a bar magnet is freely suspended, it points in the north-south direction. The tip which points to the geographic north is called the north pole and the tip which points to the geographic south is called the south pole. This is also known as its directive property.
There is a repulsive force when north poles (or south poles) of two magnets are brought close together. Conversely, there is an attractive force between the north pole of one and the south pole of the other. This states that unlike poles attract each other and like poles repel each other.
We cannot isolate the north or south pole of the magnets. If magnets are broken into two halves, we get two similar bar magnets with somewhat weaker properties. Unlike electric charges, isolated magnetic north and south poles known as magnetic monopoles do not exist.
