(a) Is the magnitude of the magnetic force experienced by proton 2 greater than, less than, or equal to the force experienced by proton 1? (b) Choose the best explanation from among the following: The protons experience the same force because the magnetic field is the same and their speeds are the same. Proton 1 experiences the greater force because it moves at right angles to the magnetic field. Proton 2 experiences the greater force because it moves in the same direction as the magnetic field.Īn electron moves with constant velocity through a region of space that is free of magnetic fields. Can one conclude that the electric field is zero in this region? Explain. If an electric field exist in this region of space, and no magnetic field is present, the electric field will exert a force on the electron and causes it to accelerate.ĬE An electron moves west to east in the continental United States Does the magnetic force experienced by the electron point ma direction that is generally north. the magnetic field in the continental United States points primarily towards the north Consider an electron moving from west to east in the continental United States The velocity vector will point towards east and magnetic field point towards north Recall the Earth has its own magnetic fiela The field generated is similar to the one generated by a bar magnet with its pole near to the geographical pole of the EarthS Currently. Use the right hand rule to find the direction of magnetic force. According to right hand rule, the direction of magnetic force will be the direction of your thumb when you curl your right handįingers from velocity vector to magnetic field vector So. here by right hand rule, the magnetic force will be towards upwards. However here the particle is an electron which is a negativelyĬharged particle. reverse the direction found by right hand rule to get the true direction of magnetic force. Therefore, here the magnetic force is on the electron is downwardsĪn electron moves with constant velocity through a region of space that is Free of electric fields. In a uniform electric field, the force on a charged particle is always in the same direction, leading to parabolic trajectories In a uniform magnetic field, the force of charged particles is always right angles to the motion, resulting the circular paths (or) helical trajectoriesĮxperiences a magnetic force in the positive y direction What is the direction of the magnetic field?Īn electron moving in the positive x-direction at right angles to a magnetic field, experiences a magnetic force in the positive y-direction The magnetic field is in the positive z-directionĭescribe how the motion of a charged particle can be used to distinguish between an electric and a magnetic field Can one conclude that the magnetic field is zero in this region? Explain.ĬE An electron moving in the positive x direction, at right angles to a magnetic field. a charged particle experiences a force due to an electric field whether it is moving (or) at rest in the magnetic field, the particle must be moving to experience a force.Įxplain how a charged particle moving in a circle of small radius can take the same amount of time to complete an orbit as an identical particle orbiting in a circle of large radius. The radius of curvature is proportional to the speed of the par1icle It follows that the particle moving in a circle of large radius has a proportionally larger speed than the particle moving in aĬircle of small radius.
