Semantics..
Solenoid in the CAR WORLD is pretty much the term used for a HEAVY DUTY HIGH CURRENT "relay" and is typically designed for SHORT TERM INTERMITTENT USAGE and main usage is for the starter.. They are used so you do not have to run 2ga or heavier wire to your ignition key switch..
Looks like this..
"Relays" are typically much lower current and can have intermittent duty or continuous duty, tend to be much smaller handle far less current..
Can look like this Bosch style 12V relay..
or even micro miniature relays that are mounted to circuit boards..
Yes, you can have "solenoid motors" which basically you have a heavy electromagnet with a hole inside attract a steel pin and the pin can be attached to other mechanical linkages and or close or open electrical "contacts". Solenoid coils tend to draw a heavy current, they have to since they are designed to move heavy spring loads.
Relays typically have an electromagnet with a fixed steel core and when magnetized it pulls the relay contacts open and or shut depending on the design..
