But tennis balls don’t contain any ferromagnetic metal… they’d just sit in the gauss cannon and do nothing while it wastes inordinate amounts of energy.
True, but fixable. Have a metal plug/plunger in the barrel that is designed to be pulled by the coils but not to exit the cannon. Push the plug back past the chamber, load the random non-metal object, and the plug will push the object down the barrel and launch it.

That’s what I did for my coil-gun ping pong ball launcher.
Get them really wet and use paramagnetism. (https://en.wikipedia.org/wiki/Paramagnetism)
