Magic Angle

Magic angle is a value of group of angle of an electron microscope at which the measured energy-loss spectrum "magically" becomes independent of the tilt-angle of the sample in relation with the beam direction. The "Magic" angle depends on the incoming electron energy, which is a fixed one, and on the energy-loss suffered by the electron.

The magic angle is used in magnetic resonance imaging. When you draw an imaginary diagonal line from the bottom corner of the inside of a cube to the opposite inner top corner of the cube, the angle formed between that diagonal line and the vertical line rising from the bottom corner is called the "Magic Angle".
