Aluminium moka pots aren't. Copper bottomed pots usually aren't. Woks don't really work without a flame. Bain-maries that work on induction tops are about 50:50.
The only thing I miss from gas is my wok. All other cooking on induction is superior. Definitely worth sacrificing a few old pots for. I would love a good wok solution though.
Bialetti makes excellent moka pots for induction. I find it even better on induction stove to control the flow as you can basically leave it on "5" and coffee slowly pours out. Much harder with real fire.
