We are using cookies to give you the best experience on our website. Rutherford proposed that they try to see if any alpha particles would bounce back, that is, not traverse the foil but be deflected by over 90 degrees back toward the direction from which the particle had originated. This force is caused by the interaction between charged particles and the electromagnetic field. The direction of deflection which can be determined by Fleming's left hand rule demonstrates that they must be positively charged. We are using cookies to give you the best experience on our website. If the field is in a vacuum, the magnetic field is the dominant factor determining the motion. Discuss why this is so, and what direction would it need to be to bend the beam downward? Heat (thermic emission) produces electrons in the electron beam. 8.2 Magnetic Fields and Lines - University of Saskatchewan 2.Because they have two protons and two neutrons, alpha particles are positively charged. Therefore an alpha particle is deflected less that an beta particle in a given electric field because of its higher momentum. In magnetic fields charged particles tend to move in circles. The absorption properties of beta radiation make it useful in industrial and some medical applications. SS: Deflection of radioactive particles - Mini Physics Quick Answer, Creative Zen X Fi 2 32Gb?

The force on the $\alpha^{++}$ particle is twice that on the $\beta^-$ particle, but also the velocity of the $\alpha^{++}$ is much smaller, so it's easier to change direction. This is due to the fact that like charges repel each other. The magnetic force (Lorentz force) provides the centripetal force in this case, as Fc = mv 2 / r Since, here sin = 1 Then, the magnetic force: F = qvB Now, if the Lorentz magnetic force provides the centripetal force, therefore, these force must be equal as: qvB = mv 2 / r Solve the above expression for r as, r = mv / qB The animation below shows the deflection of radiation in a magnetic field.
