Protons in Magnetic Field

These flashcards cover key concepts regarding protons in magnetic fields, focusing on their magnetic moments, energy states, and related phenomena.

When protons are placed in a strong external magnetic field, the magnetic moments tend to align or to the external magnetic field.

parallel; anti-parallel

In a steady magnetic field, protons tend to align __ to the field, which is the lower energy state.

parallel

The unit of magnetic field strength (B0) is __ tesla (T) = 10,000 gauss.

1

The phenomenon where the magnetic moment of protons is induced to rotate around the axis of the magnetic field is known as __.

precession

Only about __ out of 1 million total protons contribute to spin excess.

10

The 'spin excess' of protons is used to generate __ signals.

MR

An analogy to the precession of a proton spin is a __.

gyroscope

When a gyroscope is tipped off axis, gravity causes it to __.

wobble

The wobbling of a tipped gyroscope has its own frequency, which is considered __ of the spinning frequency.

independent
