Bend the Charge

Fire a charge into a magnetic field. Set the field that bends it into the gate.

Physics · Class 12 · The Lorentz force · 8 simulations. For JEE, NEET and your boards.

What you'll learn

  1. Feel the field: What B means: B = F / qv
  2. Which way it bends: The push: F = q v × B
  3. Now an electron: A negative charge: the force turns round
  4. A slanted shot: Only the part across B counts: F = qvB sin θ
  5. Force across the field: A magnetic push is always at right angles to B
  6. Ride with the charge: Another frame, another field: E′ = v × B
  7. Beside a wire: A wire's field, then the push
  8. Just fails to cross: Turn back when r ≤ d
