I had the same question and can now answer it with "yes":

This Grill works on both sides on an induction hob.
This grill works on both sides on an induction hob.

Firstly, I contacted Lodge directly and a customer advisor confirmed it for me straight away. I then ordered it and tested it myself on my hob (V-Zug V4000 I604).

I hope this information will help others, especially as it is a very interesting accessory for the kitchen.

Unfortunately, I don't know. We cook with gas, so it works very well.

Hello.
I don't think so, because the plate has a frame on which it would rest. As far as I know, with induction there must be full contact with the hob.
