Magnetic field generation
What Magnetic field generation means in Physics A-Level, as defined for AQA.
Definition of Magnetic field generation
Check what you remember
Read the wording for your board, then hide it and explain Magnetic field generation in your own words. Rough notes are fine. This is a self-check, with no mark or grade.
Reference: AQA
A superconductor can carry large currents with no resistive heating, so electromagnets reach fields ordinary copper coils cannot sustain.
