Lorentz force

F = q(E + v × B)

Where: B = magnetic field (T), E = energy (J) / electric field (N/C), F = force (N), q = charge (C), v = final velocity / speed (m/s)

Solved example

Given: B = 7, E = 5, q = 10, v = 4
Find: F (force (N))

  1. Formula: F = q·(B·v + E)
  2. Substitute the values: F = 10·(4·7 + 5)
  3. Result: F = 330

Answer: F = 330

  2. Note the known values (B, E, q, v).
  3. Substitute them and simplify to find F.
  4. Use the calculator above to solve for any letter.

Frequently asked questions

What is the formula for Lorentz force?

The formula is F = q(E + v × B), where B = magnetic field (T), E = energy (J) / electric field (N/C), F = force (N), q = charge (C), v = final velocity / speed (m/s).

What is Lorentz force when B = 7, E = 5, q = 10, v = 4?

F = 330. Substitute the values into F = q(E + v × B) and simplify.
