Force on a current-carrying conductor
20.2What the syllabus asks of you
- understand that a force might act on a current-carrying conductor placed in a magnetic field
- recall and use the equation F = BIL sin θ, with directions as interpreted by Fleming’s left-hand rule
- define magnetic flux density as the force acting per unit current per unit length on a wire placed at right- angles to the magnetic field
