If, when you turn the ignition switch on, the points happen to be in the closed position, then current will flow thru the coil and it will begin to warm. If the points just happen to be open, no current flows and the coil will stay at the ambient temperature.

Working coils generate heat so yes, when the car is running they can get quite warm.
