Catalysts
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.
True

AB + C + B is not an equation: an equation requires two sets of compounds on either side of an equality sign. Furthermore, it cannot be any of the following types of reactions because there is nothing following.
Magnetic fields can be created by charges or the flow of current.
Your feet get electrons from the carpet which produces static electricity. If you touch someone afterwards, you will most likely shock them.
False. The atom that has the same number of protons as it has electrons is a neutral atom.
