The following text describes the origin of the electron magnetic moment and gives the formula for the magnetic moment of an atom.

An atom's magnetic moment has three origin:

• The magnetic moment of electrons(spin magnetic moment)
• The magnetic moment of electrons related to their orbital motion (orbital magnetic moment)
• The magnetic moment of the nucleus.

The magnetic moment of a single electron is μ =-√3/4*gS*μB

• gS is denotes as the g-factor of the electron's spin and it’s value is 2.0023.
• μB be the Bohr magneton and it is 9.274 x 10^-24J/T

An electron has an intrinsic magnetic moment for its spin.In the other side, implies that the spin has nothing to do with the actual spinning of an electron. The g-factor is a relationship between the magnetic moment and angular momentum.

The sum of an atom's spin and orbital magnetic moments is its total magnetic moment. It is not, however, a straightforward sum according to quantum mechanics laws.The formula is μ=-gJ*μB*√(J*(J+1))

• Where, gJ be the g-factor taken combined for spin and oribital
• J be the quantum number

Question 1: What will be the magnetic moment of the substance, if the spinning of an electron is 10.586 with 10L of actual orbital contribution and the angular momentum is 15J.

Solution:

Consider the problem, we have

The sum (ordinary) of spins of all electrons be S = 10.586

The sum of orbital quantum numbers of all electrons be L=10

The quantum number describing together the spin and orbital contributions, J = 15

We know the formula to calculate Magnetic Moment μ = -gJ*μB*√(J*(J+1))

Here, μB = 9.274 * 10^-24 J/T is the Bohr magneton and gJ = 3/2 + (S(S+1) - L(L+1))/(2J*(J+1))

gJ = 3/2 + (10.586*(10.586+1) - 10*(10+1))/(2*15*(15+1))

Substituting the inputs, we get the following equation for Magnetic Moment:

μ = -9.274*10^-24*√(15*(15+1))

As a result,The magnetic moment of single electron(μ) is -23.65μB

1. What is magnetic moment?

The magnetic strength and orientation of a magnet or other item that produces a magnetic field are defined as magnetic moment. The magnetic moment is a quantity that can be expressed as a vector. The items have a tendency to align themselves so that the magnetic moment vector aligns with the magnetic field lines.

2. How do you calculate an atom's magnetic moment using calculator?

• The magnetic moment of an atom can be calculated using the simple formula:μ=-gJ*B*(J*(J+1)).
• Substitute all of the values into the input field
• Press calculate button to find the atom magnetic moment.

3. How do you determine the magnetic moment?

If the sample's molecular mass (M) is 312.8236 g/mol and the maximum magnetization (Ms) is 0.088 emu/g, the magnetization in terms of Bohr magneton per formula unit may be determined using the formula μB/ f.u. = M * Ms/5585.
