Electromagnetism: school bell electromagnet efficiency shows Draw the magnetic field pattern for a straight wire carrying a current. because magnetic effects depend on field direction, current or changing magnetic flux.

Electromagnetism: school bell electromagnet efficiency shows Draw the magnetic field pattern for a straight wire carrying a current. because magnetic effects depend on field direction, current or changing magnetic flux. It is correct because it anchors the response to Electromagnetism, uses the relevant magnetic field, coil, current or induction evidence, and avoids mixing motor, generator and transformer ideas. The school bell electromagnet efficiency detail makes the option distinct from nearby objectives while still testing the same AQA GCSE Physics learning objective.
