(a) In what direction should the magnetic field be applied? Higher level: A positron (Beta + or +) would be deflected in a similar manner to the beta - particle but in the opposite direction because it has a positive charge. Magnetic field can change the direction of alpha and beta particles as both are charged but do not change their speed. The component of the velocity perpendicular to the magnetic field produces a magnetic force perpendicular to both this velocity and the field: \[\begin{align} v_{perp} &= v \, \sin \theta \\[4pt] v_{para} &= v \, \cos \theta. It is related to the fields used in cyclotrons and betatrons. Therefore an alpha particle is deflected less that an beta particle in a given electric field because of its higher momentum. 3096 people watching, Top Answer Update for question: "arthur murray dance party"?
