When alpha and beta particles move in magnetic fields they experience a deflecting force – provided their motion is not parallel to the field.
When alpha and beta rays are subjected to a magnetic field?
When α and β rays are subjected to a magnetic fieldwhich is perpendicular to the direction of their motion, with their same speed.
How does an alpha particle move in a magnetic field?
Alpha particles in a magnetic field Alpha particles are deflected by a magnetic field confirming that they must carry a charge. The direction of deflection which can be determined by Fleming's left hand rule demonstrates that they must be positively charged.
Why does an alpha particle deflect less than a beta particle in a magnetic field?
But despite the greater speed, the larger mass makes the alpha particle have a lot more momentum than the beta particle. Therefore an alpha particle is deflected less that an beta particle in a given electric field because of its higher momentum.
Why beta rays are deflected by magnetic field?
Alpha and beta radiations are charged particles. Alpha is positively charged and beta is negatively charged. Hence these are deflected in an electric or magnetic field whereas gamma radiations uncharged particles or neutral and therefore cannot deflect in an electric or magnetic field.
When alpha and beta rays pass through a magnetic field their paths change?
A magnetic field (only one pole is shown) affects radioactive rays differently depending on the type of ray. Alpha rays (heavy, positively charged particles) are deflected slightly in one direction. Beta rays (light, negatively charged electrons) are deflected strongly in the opposite direction.
Are alpha particles deflected by a magnetic field?
Alpha and beta radiations are charged particles. Alpha is positively charged and beta is negatively charged. Hence these are deflected in an electric or magnetic field whereas gamma radiations uncharged particles or neutral and therefore cannot deflect in an electric or magnetic field.
Is an alpha particle positively charged enters a magnetic field?
AN alpha-particle ( WHICH is a POSITIVELY charged Particle) ENTERS, A UNIFORM MAGNETIC FIELD AT RIGHT ANGLE TO IT.
Why are beta particles deflected more in an electric field?
Beta particles are negatively charged. Beta particles are fast-moving electrons with a very low mass and so have a high charge to mass density. They are deflected much more than the heavier alpha particles due to this charge to mass density. Was this answer helpful?
Why do alpha particles deflected more?
This is due to the fact that like charges repel each other. As the positively charged alpha particle would fly through the foil it would come in proximity with the positively charge nucleus of the atom. This in turn either deflected the particle or adjusted its path.
