Concept information
Preferred term
magnetic rigidity
Definition
- In plasma physics, a quantity that describes the resistance of a charged particle to change its direction of motion under the influence of a perpendicular magnetic field. Rigidity is defined as: R = r_LBc = (pc)/(Ze), where r_L is the Larmor radius, B is magnetic induction, c is the speed of light, p is the momentum of the particle, Z is atomic number, and e the electron charge. Since pc has the dimensions of energy and e the dimensions of charge, rigidity has the dimensions of volts (a 10 GeV proton has a rigidity of 10 GV). In cosmic ray studies, the energies of cosmic rays are often quoted in terms of their rigidities, rather than their energies per nucleon.
