- Consider a magnetic force acting on an electric charge in a uniform magnetic field. Which of the following statements are true? a) A magnetic force is exerted on a stationary electric charge in a uniform magnetic field. b) The direction of the magnetic force acting on a moving charge in a magnetic field is perpendicular to the direction of the magnetic field. c) A magnetic force is exerted on an electric charge moving through a uniform magnetic field. d) An electric charge moving parallel to a magnetic field experiences a magnetic force. e) The direction of the magnetic force acting on a moving electric charge in a magnetic field is perpendicular to the direction of motion. f) An electric charge moving perpendicular to a magnetic field experiences a magnetic force.A particle with unknown properties moves into a region of space containing both a uniform electric field and a uniform magnetic field, as shown below. The particle begins to deviate upwards from its original trajectory. How do the magnitudes of the two forces compare? OB The electric force is stronger than the magnetic force The magnetic force is stronger than the electric force А. В. С. The electric force and the magnetic forceare equal in magnitude (but nonzero) The electric force and the magnetic force are both exactly zero Nothing can be determined without additional information D.

- A proton is moving to the right above a horizontal wire that carries a current to the right. What is the direction of the magnetic force on the proton?When a charged particle moves perpendicularly to the direction of a uniform magnetic field, the direction of the magnetic force is perpendicular to both the direction of the magnetic field and the direction of the velocity of the charged particle. Accordingly, the charge begins to move in a circular path. Since the direction of the magnetic force is toward the center of the circular path the charged particle moves along, the magnetic force is a centripetal force (recall centripetal forces from chapter 5 of the text, covered in PHY 2010). A schematic of such motion is shown below. The "X"s represent the magnetic field that is directed into the plane of this screen. The direction of velocity and magnetic force lie within the plane of this screen and are at right angles to one another, as shown below. If a charge of magnitude 7.45x10-17C, with speed 4.66x106 m/s, and mass 7.12x10-25kg moves within the magnetic field of magnitude 3.96x10-2T, what is the resulting radius of the path…Which one of the following statements is true regarding the magnetic force on a current carrying wire. The force either parallel to the length of the wire or parallel to the magnetic field. The force is independent of the current in the wire. The force is always perpendicular to both the length of the wire and the magnetic field. The magnetic force is proportional to the speed at which the wire is moving.
