12.2.A—Describe the magnetic field produced by moving charged objects

Describe the magnetic field produced by moving charged objects.

• A single moving charged object produces a magnetic field.
  • i. The magnetic field at a particular point produced by a moving charged object depends on the object’s velocity and the distance between the point and the object.
  • ii. At a point in space, the direction of the magnetic field produced by a moving charged object is perpendicular to both the velocity of the object and the position vector from the object to that point in space and can be determined using the right-hand rule.
  • iii. The magnitude of the magnetic field is a maximum when the velocity vector and the position vector from the object to that point in space are perpendicular.
