"Electric vs Magnetic Fields: Know the difference or lose points ⚡🧲
Electric fields affect ALL charges (moving or stationary). Magnetic fields ONLY affect MOVING charges. This is why a stationary charge feels electric force but zero magnetic force - and the MCAT loves testing this!
High-yield applications:
- Mass spectrometers - MRI machines - Particle accelerators - Nerve conduction vs medical imaging
Pro tip: When you see a physics passage, ask ""Is the charge moving?"" That immediately tells you which forces matter and eliminates wrong answers.
Master the right-hand rule until it's automatic - you'll need it under time pressure on test day!
