Kitchen without a magnetic wall

I have just moved in to a new house, but I realized that the kitchen wall has no magnet.
In my old apartment, I have a lot of kitchenware, accessories and hooks that sticks to the magnet wall.

I went to Daiso and buy some metal plates. But it's too weak, when I hang my pans, it fell off.
Any tips how to use my magnetic kitchenware on the non-magnetic kitchen walls again.

Now all my magnetic kitchenware are useless, but I don't want to throw them away, it's too もったいない
