{\rm{\red{\underline{\underline{Magnet:-}}}}}

⇒ Magnet is a substance which attract iron or iron like substances.

{\rm{\blue{\underline{\underline{Types\;Of\;Magnet:-}}}}}

1). Natural Magnet: These are divided into two parts,

a). Load Stone (Fe2O3).

b). Earth.

2). Artificial Magnet: These are divided into two parts,

a). Permanent magnet: These are further divided into three types.

  • Bar magnet.
  • U shape magnet.
  • Horse shoe magnet.

b). Temporary magnet: These are divided in one part,

  • Electro magnet.

{\rm{\green{\underline{\underline{Bar\;Magnet:-}}}}}

  • A bar magnet is a rectangular object that has a magnetic field.
  • It is usually made of iron and steel, but it can also be made of any ferromagnetic substances or ferromagnetic composite.
  • This is a permanent magnet.

{\rm{\pink{\underline{\underline{Properties\;Of\;Bar\;Magnet:-}}}}}

  • Magnetic lines of ores starts from north and towards south outside the magnet.
  • A freely suspended magnet always point out north to south direction that is it shows directive property.
  • Same poles of a magnet shows the repulsion while unlike shows alteration property.

{\rm{\orange{\underline{\underline{Horseshoe\;Magnet:-}}}}}

  • A horseshoe magnet is a U-shaped metal object that produces a magnetic field.
  • This magnetic field is invisible, but is responsible for a magnet's notable pull on other metal objects.
  • It is a permanent magnet.

\large{\mathcal{\red{\underline{MAGNET:-}}}}

  • A magnet is a material or object that produces a magnetic field.

  • This magnetic field is invisible but is responsible for the most notable property of a magnet: a force that pulls on other ferromagnetic materials, such as iron, and attracts or repels other magnets.

\large{\mathcal{\purple{\underline{THERE\;IS\;THREE\;TYPES\;OF\;MAGNET:-}}}}

  • Permanent Magnet.
  • Temporary Magnet.
  • Electromagnet.

\large{\mathcal{\orange{\underline{PERMANENT\;MAGNET:-}}}}

  • Permanent magnets are those which retain their magnetism when once magnetized. Most of the magnets we come across in our daily life are permanent magnets.

  • Example Bar magnet, horse shoe magnet etc.

\large{\mathcal{\blue{\underline{TEMPORARY\;MAGNET:-}}}}

  • Temporary magnets show magnetism only when they are kept in the vicinity of some strong magnetic field.

  • They lose their magnetism when the field is removed.

\large{\mathcal{\pink{\underline{ELECTROMAGNET:-}}}}  

  • Electromagnets work on the principal of electromagnetic induction. They are usually made by wounding wire around a soft iron core.

  • Their magnetism can be changed by changing the amount of current.
