alleryElectric currents create what, which is used in motors and generators?
AMagnetic fields
BGravity waves
CSound pressure
DCold zones
Answer & Solution
Correct answer: A. Magnetic fields
1. Electric currents create magnetic fields used in motors, generators, inductors and transformers.
2. Gravity waves, sound pressure and cold zones are not produced this way.
3. So magnetic fields are correct.
