Revise Edexcel GCSE Physics 12.3.3 Force on a conductor with the question bank and revision guides.
Use the equation: force on a conductor at right angles to a magnetic field carrying a current (newton, N) = magnetic flux density (tesla, T or newton per ampere metre, N/A m) × current (ampere, A) × length (metre, m); F = B × I × l.
