SUMMARY

The discussion centers on the direction of forces acting on moving charges in a magnetic field, specifically in the context of the equation F = q v × B. The forces are confirmed to be orthogonal to both the magnetic field (B-field) direction and the motion of the charges, resulting in forces that are oriented up and down in the provided diagram. The right-hand rule is emphasized as a critical tool for determining the correct direction of these forces.

PREREQUISITES
  • Understanding of electromagnetic theory
  • Familiarity with the right-hand rule for cross products
  • Knowledge of the Lorentz force equation (F = q v × B)
  • Basic concepts of magnetic fields and current flow
NEXT STEPS
  • Study the application of the Lorentz force in various electromagnetic scenarios
  • Learn about the right-hand rule and its applications in physics
  • Explore the implications of magnetic fields on charged particles
  • Investigate the behavior of currents in different magnetic environments
USEFUL FOR

Students of physics, educators teaching electromagnetism, and professionals working with electromagnetic systems will benefit from this discussion.

they are supposed to be inide and outside the page

come come they go to be up and down?

The forces on the moving charges in the wires will be orthogonal to both the B-field direction and the direction of the motion of the charges. Hence, the forces have to be up and down in that diagram, since both B and the current directions lie in the plane of the page.

Use the equation F = q v X B to help you get a feel for the directions involved. Use the right-hand rule for that cross product in order to get the correct force direction. Does that make sense now?
