Meaning of Magnetism

What is Magnetism:

The phenomenon of attraction and repulsion of certain metals and magnets is known as magnetism.

In physics, magnetism is defined as the attractive force of magnets that have a positive and a negative pole, known as a dipole.

In this way, the magnetic dipole property informs that like poles repel and opposite poles attract.

In a figurative sense, magnetism refers to the attraction or desire that one person feels for another. Also, magnetism is defined as the state of unconsciousness that is achieved by techniques of suggestion or hypnotism and is characterized by an artificial sleep or induced by foreign agents.

Earth magnetism

Earth's magnetism manifests itself in the effect of the known magnetic needle on the compass. The north pole of the magnetized needle is its magnetic north pole. In magnetism, opposite poles attract, therefore the needle is attracted to the Earth's magnetic south pole, which happens to be the geographic North Pole.

Magnetic fields surround electrical currents that are supposed to be the source of their generation. These currents, under the dynamo effect, create surrounding electrical currents in the Earth's metallic liquid outer core (10% nickel, 5% iron).
