โšก Lorentz Force Lab

Master the interaction between charged particles and electromagnetic fields

Difficulty: โ— Medium

๐Ÿ“ Physics Formulas
F = q(E + v ร— B)
Lorentz Force Law (Vector Form)
r = mv / qB
Gyroradius
f = qB / 2ฯ€m
Cyclotron Frequency
๐Ÿ“š Key Concepts
  • Magnetic force is perpendicular to both velocity and field
  • Electric force is parallel to the electric field
  • Positive charges curve opposite to negative charges
  • Magnetic force does no work (speed stays constant)
  • Particles spiral in combined fields
๐Ÿ”ฌ Try This
  • Switch charge polarity - how does path change?
  • Increase magnetic field - notice the radius?
  • Add electric field perpendicular to motion
  • Launch at different angles in both fields
  • Compare electron vs proton motion (mass ratio)
