Can an electric field exist without a magnetic field, and can magnetic field exist without an electric field?
Not happy with the second half of your answer.Electric fields can exist without a magnetic field - consider a stationary point charge.
Magnetic fields cannot exist without any E field component because there are no magnetic monopoles.
Not happy with the second half of your answer.
A stationary electric charge creates an electric field.
A changing electric field creates a magnetic field.
A changing magnetic field creates an electric field.
Likewise, a stationary dipole magnet (e.g. a magnetized lump of iron) creates a magnetic field.
Just the way I learned it.
Since it aligns with Maxwell's statements, it is most likely the "expected" answer if questioned in first-year physics.
What you guys are discussing is far beyond my understanding, but as far as the MCAT goes, is going with Cawolf's original answer okay?Oh, well if you're gonna get all technical on me ;-)
No I was just thinking I might need to know this for the MCAT, thanks!I doubt you would see such a topic. Do you have a sample question that makes you think otherwise?
