\huge\mathbb{\purple{DEF. \: OF \: MAGNET}}

A magnet is defined as

An object which is capable of producing magnetic field and attracting unlike poles and repelling like poles.

\huge\mathbb{\pink{PROP. \: OF \: MAGNET}}

Following are the basic properties of magnet:

  • When a magnet is dipped in iron filings, we can observe that the iron filings cling to the end of the magnet as the attraction is maximum at the ends of the magnet. These ends are known as poles of the magnets.
  • Magnetic poles always exist in pairs.
  • Whenever a magnet is suspended freely in mid-air, it always points towards north-south direction. Pole pointing towards geographic north is known as the North Pole and the pole pointing towards geographic south is known as the South Pole.
  • Like poles repel while unlike poles attract.
  • The magnetic force between the two magnets is greater when the distance between these magnets are lesser.

\huge\mathbb{\purple{TYPE'S \: OF \: MAGNET}}

There are three types of magnets, and they are as follows:

  • Permanent magnet
  • Temporary magnet
  • Electromagnets

\huge\mathbb{\pink{PERMANENT MAGNET}}

Permanent magnets are those magnets that are commonly used. They are known as permanent magnets because they do not lose their magnetic property once they are magnetized.

Following are the ways to demagnetize the permanent magnets:

  • Exposing magnets to extreme temperatures.
  • The magnetic attraction between the magnet’s atoms gets loosen when they are hammered.
  • Stroking one magnet with the other in an inappropriate manner will reduce the magnetic strength.

\huge\mathbb{\pink{TEMPORARY\: MAGNET}}

Temporary magnets can be magnetized in the presence of a magnetic field. When the magnetic field is removed, these materials lose their magnetic property. Iron nails and paper-clips are examples of the temporary magnet.

\huge\mathbb{\purple{ELECTRO: MAGNET}}

Electromagnets consist of a coil of wire wrapped around the metal core made from iron. When this material is exposed to an electric current, the magnetic field is generated making the material behave like a magnet. The strength of the magnetic field can be controlled by controlling the electric current.

\huge\mathbb{\pink{CHAR. \: OF \: MAGNET}}

Following are the characteristics of magnet:

  • Attractive property: This property proves that the magnetic strength at the ends of the poles is strong.
  • Directive property: This property helps to understand which pole of the magnet is north and south by suspending the magnet in mid-air.
  • Law of magnetic poles: Like poles repel while unlike poles attract.
  • Pair property: When a magnet is cut into two pieces, both the pieces will have the North Pole and the South Pole.
  • Sure test of magnetization: This test is conducted to check if a given rod is magnetized or not by checking either the attraction or the repulsion of the iron rod and magnet.
