Question

What is magnet? Explain Properly.​

Answer 1

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

⇒ 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.

Answer 2

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

• 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.
