Takeaways

• 😀 The interaction between magnetic fields and moving charges creates distinct motion patterns, such as spirals and circles.
• 😀 A velocity selector is a device used to filter charged particles based on their velocity.
• 😀 The radius of deflection for a charged particle in a magnetic field depends on its velocity; faster particles have larger deflection radii.
• 😀 The electric force acting on a charged particle is directed towards the lower potential plate in a parallel plate setup.
• 😀 Without intervention, a charged particle in an electric field will follow a parabolic trajectory due to the electric force acting on it.
• 😀 To achieve straight-line motion in a velocity selector, the magnetic force must equal the electric force acting on the particle.
• 😀 Fleming's Left Hand Rule is used to determine the direction of magnetic force, electric current, and magnetic field.
• 😀 The trajectory of a charged particle will be circular if only a magnetic field is present and no electric field is applied.
• 😀 If the electric force is greater than the magnetic force, the particle will deflect downwards; if the magnetic force is greater, it will deflect upwards.
• 😀 The velocity of a particle that travels undeviated in a velocity selector must equal the ratio of electric field strength to magnetic field strength (E/B).
