The force on a straight conductor of length L carrying current I in a uniform magnetic field B is, in vector form?

  • AF = I(L × B)
  • BF = I(L · B)
  • CF = B/(IL)
  • DF = IL/B
Report an error
Correct Answer: A. F = I(L × B)
Explanation: The magnetic force on a straight current element is F=I(L×B).
Reference: Standard electromagnetic theory: magnetic force
