Question

What is the difference between a relay and a solenoid?

Answer 1

Answer:

"A relay is in essence a switch with two positions, on and off. A solenoid, meanwhile, enables mechanical components to physically move and change position, for example, a starter motor engaging a flywheel."

That's not really a clear answer to me. The solonoid doesn't doesn't make the starter move. It just transfers power to it so that it can move. Sounds a lot like a relay to me
