The principle behind an MR scan

superconducting coil produce a flux density of between 1 and 2T.

produces a very small electromagnetic signal at the Larmor frequency

relies on the magnetic properties of the electron

external magnetic field is applied to the hydrogen atom in our body

the protons de-excite: they return to the original state and emit RF signals.

The magnetic flux (Φ) can be zero when

The angle between magnetic field and the surface area is zero

The angle between magnetic field and the surface area is 90˚

The angle between magnetic field and the normal is 90˚

the magnetic field is exactly parallel to cross-sectional area

the magnetic field is exactly perpendicular to cross-sectional area
