What is the magnetic moment of the loop?

Reasoning: The torque exerted on the loop is τ = μ × B

μ × B

The Bohr magneton is the magnitude of the magnetic dipole moment of an electron orbiting an atom with such angular momentum. According to the Bohr model, this is the ground state, i.e. the state of lowest possible energy.

What is the magnetic moment of a circle?

M=Iπr2.

What is the magnitude of the magnetic moment of the loop?

For a current loop, this definition leads to the magnitude of the magnetic dipole moment equaling the product of the current times the area of the loop. Further, this definition allows the calculation of the expected magnetic moment for any known macroscopic current distribution.

What is meant by magnetic moment?

Definition of magnetic moment

: a vector quantity that is a measure of the torque exerted on a magnetic system (such as a bar magnet or dipole) when placed in a magnetic field and that for a magnet is the product of the distance between its poles and the strength of either pole.

What is the magnetic moment of a current carrying circular coil?

1 Answer. Explanation: The magnetic moment of a current carrying conductor = i.n πr² = niA.

What is formula of magnetic dipole moment?

The strength of that tiny magnet, the magnetic dipole moment m, is given by m = NIA, giving the units - Ampere meter square. The magnetic dipole moment is a vector quantity and its direction is given by the right-hand thumb rule.

What is the unit of magnetic moment of a current carrying a closed loop?

<br> Thus the current loop can be regarded as a magnetic dipole which produces its magnetic field and magnetic dipole moment of the current loop is equal to the product of ampere turns and area of current loop. SI unit of magnetic dipole moment is `A-m^2`.

What is magnetic moment of an electron revolving around the nucleus of an atom?

An electron in the ground state of hydrogen atom in revolving in anticlockwise direction in a circular orbit of radius R (see fig) If the expression for the orbital magnetic moment of the electron is M=Xπmeh​.

What is magnetic moment of nucleus?

The nuclear magnetic moment is the magnetic moment of an atomic nucleus and arises from the spin of the protons and neutrons. It is mainly a magnetic dipole moment; the quadrupole moment does cause some small shifts in the hyperfine structure as well.

What is the magnetic dipole moment of an electron revolving around the nucleus of an atom?

Its value is 8.8 × 10¹⁰ C kg^-1.

How do you find the magnetic moment of a vector?

For any other direction the energy (E) of the magnetic moment (µ) would be given by the vector dot product: E = − µ • Bo.

What is magnetic dipole moment unit?

Magnetic dipole moments have dimensions of current times area or energy divided by magnetic flux density. In the metre–kilogram– second–ampere and SI systems, the specific unit for dipole moment is ampere-square metre.

What happens when a current carrying loop is placed in a uniform magnetic field?

EXPLANATION: If a rectangular loop carrying a steady current is placed in a uniform magnetic field then it will experience a torque. The net force on the loop will be zero.

What is the SI unit of pole strength?

Solution : SI unit of pole strength is ampere-metre and SI unit of magnetic moment is ampere `meter^2`.

What is magnetic moment Toppr?

The magnetic moment of a magnet ( or current loop) is defined as the maximum value of torque acting on a magnet when it is placed in a magnetic field of 1 T.

What is the magnetic moment of cr2+?

Hence, the magnetic moment of Cr²⁺ is 4.90 BM.

What do you understand by magnetic moment of a neutron?

The neutron magnetic moment is the intrinsic magnetic dipole moment of the neutron, symbol μ_n. Protons and neutrons, both nucleons, comprise the nucleus of atoms, and both nucleons behave as small magnets whose strengths are measured by their magnetic moments.

How do you find the magnetic moment of a proton?

For a proton, the end result of this calculation is that the magnetic moment of the neutron is given by μ_p = 4/3 μ_u − 1/3 μ_d, where μ_u and μ_d are the magnetic moments for the up and down quarks, respectively. This result combines the intrinsic magnetic moments of the quarks with their orbital magnetic moments.

What is the spin of the nucleus?

Hydrogen nuclei (protons) have magnetic properties, called nuclear spin. They behave like tiny rotating magnets, represented by vectors. The sum of all the tiny magnetic fields of each spin is called net magnetization or macroscopic magnetization. Normally, the direction of these vectors is randomly distributed.
