Chapter 1-1 What is magnetism?
Chapter 1-1 What is magnetism? Magnetism has many different interpretations, that’s why we wrote this article to help you get the most accurate answer. Magnetism is the force exerted by two magnets when they attract or repel each other. Magnetism is what causes the movement of charges. All substances are made up of tiny units called atoms. Each atom has electrons, charged particles. Spinning like tops, electrons revolve around the nucleus or core of the atom. Their movement generates an electric current and makes each Electron act like a small magnet.
In most substances, the same number of electrons rotating in opposite directions will lose their magnetism. That’s why materials like cloth or paper are said to be weakly magnetic. In substances such as iron, cobalt, and nickel, the majority of electrons rotate in the same direction. that makes the atoms in these substances strongly magnetic – yet they are not magnets yet.
To become magnetized, another strongly magnetic substance must enter the magnetic field of an existing magnet. A magnetic field is a place around a magnet that has a magnetic force. All magnets have north and south poles. Poles of opposite sign attract each other and poles of the same sign repel each other. When you rub a piece of iron along a magnet, the north poles of the atoms in the iron will point up in the same direction. The force created by the bonding atoms will form a magnetic field. The piece of iron is already a magnet.
There are some substances that are susceptible to magnetization when an electric current is applied. When current flows through the coil, it creates a magnetic field. Therefore, the field around the coil will disappear when the current is just turned off.

The series of popular magnetism questions
Learn the meaning of Magnetic
Magnetism is a type of fragile magnetism produced by changing the orbital motion of electrons due to a forced magnetic field. When the source of the induced magnetic field is removed, the magnetism of the given material is lost.
What are the two poles of a magnet?
A magnet is a magnetic source with two poles: a north pole and a south pole, and a magnetic field that forms from the passages from the north pole ( n ) to the south pole ( s ).
What is a permanent magnet?
A permanent magnet is an object made of hard material that has the ability to keep the magnetism from being lost. Magnets are commonly used to stick annotations on boards and other metals.
Example question
Question 1: magnetism is caused by the ….. of electric charges.
Answer: motion
Why: because magnetism is caused by the movement of electrical charges.
Question 2: What happens when the north and south magnetic poles are close to each other?
Answer: Will attract each other
Why: Because two opposite poles will attract each other, and if two poles are the same, they will repel each other.
Question 3: In magnetism, electrons all rotate in ………..
Answer: The same direction
Question 4: What is the main element used to make a magnet?
Answer: The main element is iron
Question 5 (True/False): The compass points north because the Earth is basically a giant magnet
Answer: True
