| The ''cyclotron frequency'' or ''gyrofrequency'' is the frequency of a [[charged particle]] moving perpendicular to the direction of a uniform magnetic field ''B'' (constant magnitude and direction). Since that motion is always circular,<ref name="Physics">Physics by M. Alonso & E. Finn, Addison Wesley 1996.</ref> the cyclotron frequency is given by equality of [[centripetal force]] and magnetic [[Lorentz force]]

| By substitution for the circulation frequency <math>f = \frac{v}{2 \pi r}</math> which defines the cyclotron frequency, this leads to

Claude is her title and she completely digs that name. Interviewing is how I make a living and it's something I really enjoy. What he truly enjoys performing is to play handball but he is having difficulties to discover time for it. Arizona is her beginning place and she will by no means transfer.
