How is the force on a conductor in a magnetic field calculated?.
- A.F = B x I x L
- B.F = m x a
- C.F = q x E
- D.F = V / R
Model answer
What a good answer should say
- F = B x I x L
Explanation
Why this works
The force on a conductor in a magnetic field is calculated using the formula F = B x I x L, where F is the force, B is the magnetic flux density, I is the current, and L is the length of the conductor in the magnetic field.
