Homework Help: True/False: Magnetic Field

  1. Feb 28, 2008 #1
    2. Which of the following statements are true:
    a. a charged particle moving in a constant magnetic field can not have its speed increased by that field.
    b. the force on a charged particle moving in a magnetic field depends only on the magnitude of the velocity, not on its direction.
    c. the force on a charged particle moving in a magnetic field is independent of the velocity.
    d. the effect of a magnetic field on a charged particle is to increase its Kinetic Energy if the particle is positively charged
    e. the force on a charged particle moving in a magnetic field can be in the direction of the field
    f. a magnetic field leads to the constant acceleration of charged particles.

    You need to think of the Right Hand Rule and the implications to acceleration of a charged particle.

    ALL of these questions can be answered by looking at the form of the equation that describes the force on a charged particle due to a magnetic field. It is called the Lorentz force law, and it should be in your book or in your notes.
