What are the possible results of a coronal mass ejection hitting earth?

If we are hit by a CME what may happen? Also, can we predict them and how? What can we do to protect ourselves?

If electromagnetic forces were somehow increased equally, would it take more energy to excite atoms?

Specifically would an object with said increased electromagnetic bonds etc. exhibit appearances of being colder than they actually were due to the increased energy required to excite them?

What exactly is a magnetic particle?

I all my searches, I could never find an understandable answer explaining what magnetic particles are. Or perhaps I should ask, "Is the magnetic field composed of an actual stream of particles"? It cannot be the same as light because light doesn't bend around something the size of a bar magnet. Nor are they electrons or other atomic or subatomic particles I have heard of. I'd love to know this! - Thank You
