Despite the considerable observational efforts done, the magnetic field of the Galaxy and the extragalactic ones are still poorly known. We know the alphas must be moving from left to right(away from the source)and our second finger shows that this is the direction of the conventional current. The trick is to see whether the direction of the current you come up with from using Flemings left-hand rule is the same as the direction you know the particles are moving in (because you know they come from the source).

Thanks for contributing an answer to Physics Stack Exchange! The 82 Top Answers, Art Of War Niccolo Machiavelli? What video game is Charlie playing in Poker Face S01E07? Van Allen found that due to the contribution of particles trapped in Earths magnetic field, the flux was much higher on Earth than in outer space. Magnetic field can change the direction of alpha and beta particles as both are charged but do not change their speed. Alpha and beta move in circular paths in a magnetic field In magnetic fields charged particles tend to move in circles. How can we prove that the supernatural or paranormal doesn't exist? As an Alpha particles consist of two protons and two neutrons. It contains well written, well thought and well explained computer science and programming articles, quizzes and practice/competitive programming/company interview Questions. The deflection happens only when the particle has a charge. Is the Timing of Alpha Particle Radiation Perfectly Random? Similarly if you know the direction of the force and the direction of the magnetic field then you can infer the direction of the electric current. The charged particles must be moving in order to be affected by the magnetic field. Please visit this website to see the detailed answer. 179 Most Correct Answers, GCSE Physics Radioactivity 3 Deflection and safety, Information related to the topic deflection of alpha particles in magnetic field, Baby Monitor Cord Safety? What happens to alpha particles in a magnetic field? If the field is in a vacuum, the magnetic field is the dominant factor determining the motion. 166 Most Correct Answers, Crew Singular Or Plural? The path the particles need to take could be shortened, but this may not be economical given the experimental setup. This means that every time you visit this website you will need to enable or disable cookies again. That is what creates the helical motion. Alpha Particle. Noting that the velocity is perpendicular to the magnetic field, the magnitude of the magnetic force is reduced to \(F = qvB\). The direction of deflection which can be determined by Fleming's left hand rule demonstrates that they must be positively charged.

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. As a result, the electrons in the cathode ray are traveling in the opposite direction of conventional current when compared to what is flowing through them.
