Why it matters
This objective helps connect Electric motors (HT only) to exam-style questions, flashcards, and revision notes for The motor effect.
Quick student answer
What should you know about (HT only) State that a coil of wire carrying a current in a magnetic field tends to rotate?
Direct answer
In Physics, this page helps you answer questions about (HT only) State that a coil of wire carrying a current in a magnetic field tends to rotate within The motor effect. Focus on the key process, correct scientific terms, and how the idea links to exam-style questions. Key terms to check are Electric motors (HT only) application cue 101 and Electric motors (HT only) measurement cue 102.
Key terms
- Electric motors (HT only) application cue 101: A phone speaker coil application cue for (HT only) State that a coil of wire carrying a current in a magnetic field tends to rotate.. It helps identify the relevant magnetic field, current, transformer coil, motor effect or generator induction evidence, while keeping Electric motors (HT only) distinct from neighbouring GCSE Physics ideas.

Common trap
motor-effect force direction: avoid motors and generators: Instead, identify the exact Unit 4.7 idea in Electric motors (HT only), then explain how it links to a loudspeaker coil moving in a magnetic field and the objective to state that a coil of wire carrying a current in a magnetic field tends to rotate.
