Do electric and magnetic fields always form closed loops
🔄 Click to see definition
Definition1/11
Magnetic fields do, because there's no such thing as an isolated
magnetic "pole",
and a magnetic line always starts and ends at opposite poles of
the same
magnetized object.
But electric fields don't. You can easily have a bundle of
isolated positive charge
over here and a bundle of isolated negative charge over there,
whereupon the
lines of the electric field start on one bundle and end on the
other bundle.
But electric field lines can also exist in closed loops, and
they do that in radio waves, where the electromagnetic field
propagates with an electric field component and a magnetic field
component, and they both form closed loops.
