WebA LEVEL. PHYSICS INTRODUCTION A magnetic field is a region in which a moving charge or a current-carrying conductor will experience a force when it is placed in it. … Web25 mei 2024 · When conductors, like copper wire, move in magnetic fields, electric fields are created. These fields, or voltages, can then drive electrical currents. This is how the electricity that we use every day is produced. Through this process of induction, large generators or “dynamos” convert mechanical energy into the electromagnetic energy … WebNotes - Topic 20 Magnetic Fields - CAIE Physics a-level - Free download as PDF File (.pdf), Text File (.txt) or read online for free. notes. notes.
