Many students have difficulty predicting the direction of the force in electromagnetism

Electricity and Magnetism

Misconception RESEARCH REVIEW

For example, by a magnetic pole near a wire or coil, by a current-carrying wire in a magnetic field, or by an electrically charged object moving in a magnetic field.

Resources to Address This

  • The Force on a Conductor in a Magnetic Field (16-19)

    This resource, aimed at 16-19 students, describes a series of demonstrations, class discussions, and practice questions on the force exerted on a moving charge.

  • The Force on a Moving Charge (16-19)

    Here you can extend the idea of a magnetic force on a current to consider moving charges.
