4.4.107 - Force on a current-carrying conductor

Be able to use the equation F = BIl sinθ and apply Fleming’s left-hand rule to current carrying conductors in a magnetic field.

Use - force on a current-carrying conductor to connect the rule to the data and decision in the question.

This matters because - force on a current-carrying conductor determines what can be inferred or chosen; begin with the stated conditions and keep the conclusion tied to the evidence.

Example: apply - force on a current-carrying conductor to one small, clearly defined case, show the key step or comparison, and explain the result in words.

Boundary: - Force on a current-carrying conductor is not a universal recommendation. Check the syllabus scope, assumptions, units and the limits of the evidence before generalising.
