:''Note 1'': The magnetic field scan is sometimes called B-scan, but this is a misnomer since the symbol B denotes the [[wikipedia:magnetic flux|magnetic flux]] density. The magnetic field strength H in a vacuum is defined in SI units as H = (1/μ<sub>0</sub>) B -M where μ<sub>0</sub> is the [[wikipedia:vacuum permeability|magnetic constant]] or permeability of the vacuum and M the [[wikipedia:magnetization|magnetization]]. B is often wrongly referred to as "magnetic field strength." | |||
== | :''Note 2'': A sector magnetic field produces a momentum/charge spectrum of an ion beam, but if all ions have the same translational energy this is equivalent to a mass spectrum. The force F on a particle with charge q and velocity ''v'' is F = q(''v'' x B). | ||
