No. Adding the cap across the coil will slow the release.

Use a second set (DP n.o.) of contacts to route power to the capacitor charging it while magnet is "on".

When the release button is pressed, the relay opens and the capacitor is connected thru nc contacts to the magnet coil. Polarity reversed.

That may not be needed. Or just connecting the discharged cap to the coil may be enough.

Max may have a standard diagram. I'd have to draw one as google didn't find one.
If possible a diagram would be great! Or just take mine and alter it. Either way thanks!

Some thing like this should work, the resistor can be replaced with a NO contact if not used, the initial value should be around the same as the resistance of the magnet.
You also need multi pole relays or double up on the lift relay.
