I've bought those ones and used both halfs inside of the tank.
Just buy and use a non coated magnet on on the outside.

I've also purchased 3 large glass cleaners/cheap mag floats and used them all over aswell.

One of the ones I bought wasnt water proof and filled up with water.
I recommend sealing the seams with super glue prior to use.
