Question

Which of the following statement is true about magnetic moments of atoms of different elements
A. All have a magnetic moment
B. None has a magnetic moment
C. All acquire a magnetic moment under external magnetic field and in same direction as the field
D. None of the above statements are accurate

Answer 1

Hint: A magnetic moment, also referred to as a magnetic dipole moment, is a measurement of an object's tendency to align with a magnetic field. A vector quantity is the magnetic moment. The magnetic moment vector frequently aligns with the magnetic field lines when the objects are positioned in that way. A magnet's magnetic moment is directed from its southern to northern poles. The magnetic field that a magnet creates is inversely related to its magnetic moment.

Complete step by step solution:
A magnetic moment depends on whether atoms in one location are aligned with atoms in another region as to what causes the magnetic moment in magnetic materials, which is determined by the spin and orbital angular momentum states of the electrons. So it's difficult to say which one has a magnetic moment and which one does not. The electron's gun, which is its orbital motion and a change in orbital motion brought on by an applied magnetic field, can produce the magnetic moment of an atom.

Hence, the correct answer is option D.

Note: Magnetometers are devices that are used to measure magnetic moments. However, not every magnetometer is oriented to capture the magnetic moment in its purest form. Some of these instruments solely detect magnetic fields; the magnetic moment is then determined from the magnetic field measurement.
