What is the formula to calculate the force on a current-carrying conductor in a magnetic field?.
- A.F = BIL
- B.F = B + I + L
- C.F = B/I + L
- D.F = BIL^2
Model answer
What a good answer should say
- F = BIL
Explanation
Why this works
The correct formula for calculating the force on a current-carrying conductor in a magnetic field is F = BIL, 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.
