Electromagnetism: scrapyard lifting magnet safety shows State that adding an iron core increases the strength of the magnetic field of a solenoid. because magnetic effects depend on field direction, current or changing magnetic flux.

Electromagnetism: scrapyard lifting magnet safety shows State that adding an iron core increases the strength of the magnetic field of a solenoid. 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 scrapyard lifting magnet safety detail makes the option distinct from nearby objectives while still testing the same AQA GCSE Physics learning objective.
