Electronic catapult? Answered

Okay. I'm going to make an electromagnet to hold the spring in place while it's compressed, and then as the power turns off, the spring will release and shoot the catapult. However, I'm not an engineer-- I'm making this for tech class. How should I design the catapult so that this will work as a triggering mechanism? In what way should I set up the spring and electromagnet relative to each other?

Thanks in advance.

Look into electronic deadbolts or those remote electric entry door lock systems. See how they work. Good luck.
