Which conclusion keeps the magnetism concept boundary clear? Context: iron-filings field pattern voltage-change. Learning objective: (HT only) State that a coil of wire carrying a current in a magnetic field tends to rotate.. Which answer is most accurate for Electric motors (HT only)?

- A.Electric motors (HT only): iron-filings field pattern voltage-change shows (HT only) State that a coil of wire carrying a current in a magnetic field tends to rotate. because magnetic effects depend on field direction, current or changing magnetic flux.
- B.It swaps motor and generator reasoning. (AC-output error).
- C.It describes gravitational force instead of magnetic force. (coil-core error).
- D.It claims induced current is supplied by a cell. (compass-response error).
