Question

write SI unit and dimension of magnetic moment ?​

Answer 1

Answer:

A loop of electric current, a bar magnet, an electron, a molecule, and a planet all have magneticmoments. ITS SI UNIT IS -- 'In the metre–kilogram– second–ampere and SI systems, the specific unit for dipole moment is ampere-square metre.

Explanation:

Answer 2

Answer:

SI unit  and dimension of Magnetic moment are A m²  and  [L]² [A] respectively.

Explanation:

• Magnetic moment (M) is a vector quantity a measure of the torque exerted on a magnetic system; when placed in a magnetic field.
• M =  i A

where,

M = Magnetic Moment

i = current

A = Area

⇒ SI unit of Magnetic moment

⇒ M =  i x A

⇒ M =  Ampere x meter²  [ SI unit of i is Ampere and area is m²]

⇒ M =  A m²  

Therefore, SI unit of Magnetic moment is A m²  

⇒ Dimension of Magnetic moment

⇒ M = A m²  

as meter falls in Length dimension and ampere is in ampere dimension

⇒ M = [A] [L]²  

Therefore, Dimension of Magnetic moment is [L]² [A]
