Question

When placed in magnetic field all the random spins of the nuclei?

Answer 1

it will bar magnet. . . .

Answer 2

When placed in a magnetic field all the random spins of the nuclei align with the magnetic field.

• Nuclear spin refers to the magnetic characteristics of hydrogen nuclei (protons).
• They behave like small spinning magnets, and their behavior is described by vectors.
• Net magnetization, also known as macroscopic magnetization, is the total of all the small magnetic fields of each spin.
• Normally, the orientation of these vectors is spread at random.
• As a result, the total of all spins results in a null net magnetization. Nuclear spins align with the external magnetic field in the presence of a substantial external magnetic field.
• Some of the spins are parallel to the field, while others are perpendicular to it (anti-parallel).
