Electromagnetism: classroom plotting compass safety shows Define an electromagnet as a solenoid with an iron core. because magnetic effects depend on field direction, current or changing magnetic flux.

Electromagnetism: classroom plotting compass safety shows Define an electromagnet as a solenoid with an iron core. 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 classroom plotting compass safety detail makes the option distinct from nearby objectives while still testing the same AQA GCSE Physics learning objective.
