What is the unit and dimension of pole strength?
From equation (1), we can find the SI unit of the magnetic pole strength. The SI unit of magnetic dipole moment is Ampere – metre squared $\left( A{{m}^{2}} \right)$ and the SI unit of length is metre $\left( m \right)$. Hence, the SI unit of magnetic pole strength is Ampere – metre $\left( Am \right)$.
What is the unit of magnetic pole strength?
(i) The SI unit of magnetic pole strength is Ampere-metre (A-m).
What is dimensional formula of strength?
The concept of dimension in maths does not have any specific dimensional formula….Dimensional Formula:
| Physical quantity | Unit | Dimensional formula |
|---|---|---|
| Electric field strength or Intensity of electric field (force/charge) | NC –1, Vm –1 | MLT –3I –1 |
What is the pole strength?
Definition of pole strength : a quantity corresponding to the amount of magnetic flux emanating from a given magnetic pole and expressed in terms of the unit magnetic pole.
What is dimensional formula of magnetic moment?
[M1L−2T0A−1]
How is pole strength measured?
A unit pole strength is defined as the strength that repels an identical pole 1 cm (m) away with a force of 1 dyne (Newton) in free space (i.e. a vacuum). The force is attractive if poles are of opposite sign and repulsive if of like sign.
How do you find the unit of pole strength?
unit of pole strength is (1) Am^2 (2) Am (3) Am^-1 (4) Am^-2. There are two possible units for magnetic pole strength in SI units, depending on how the pole force is described. If you describe this as force per unit field B, then the SI unit is the ampere-meter (A m).
What is the formula of dimension?
The equation obtained by equating a physical quantity with its dimensional formula is called a dimensional equation….Dimensions and Dimensional Formula.
| Physical Quantity | Dimensional Equation |
|---|---|
| Force (F) | F = [M L T-2] |
| Power (P) | P = [M L2 T-3] |
| Velocity (v) | v = [M L T-1] |
| Density (D) | D = [M L3 T0] |
What is magnetic moment formula?
Magnetic Moment Formula: The magnetic moment is a vector relating torque of an object to the magnetic field. This is mathematically represented as: τ = m × B.
What is unit and dimension of magnetic moment?
Answer: The magnetic moment of a magnet is a quantity that determines the torque it will experience in an externalmagnetic field. ITS SI UNIT IS — ‘In the metre–kilogram– second–ampere and SI systems, the specific unit for dipole moment is ampere-square metre.
What is the formula for the pole strength of a magnet?
According to the pole strength formula, the pole strength of a magnet is given by the ratio of magnetic moment to its effective length (called the magnetic length). SI unit of pole strength is A . m. U = -m . B An electron revolving around the nucleus of an atom, constitutes a closed current-carrying loop. The magnetic moment of an electron is,
What is the symbol of the magnetic field strength?
Furthermore, the symbol of the magnetic field strength happens to be ‘H’. Magnetic field strength is a quantitative measure of strength or the weakness of the magnetic field. Also, it is the force which a unit north pole of one-weber strength experiences at a particular point in the magnetic field. Get the huge list of Physics Formulas here
What is the dimensional formula for magnetic field?
Magnetic Field = Force × [Charge × Velocity] -1 Or, B = [M 1 L 1 T -2] × [I 1 T 1] -1 × [L T -1] -1 = [M 1 L 0 T -2 I -1 ]. Therefore, Magnetic Field is dimensionally represented as [M1 T-2 I-1]. ⇒ Check Other Dimensional Formulas:
What is the SI unit of magnetic dipole moment?
The SI unit of magnetic dipole moment is Am2 . The CGS unit is emucm2. These two units are related as, Magnetic monopoles do not exist however to draw an analogy from electrostatics, a concept of “pole strength” can be defined, which is equivalent to electric charge.
