Magnets - Copper?

[BettaCrew]

Do magnets have copper in them? I'm trying to get zucchini to sink so my rabbit snail can eat.

Stick a spoon or fork into it. Stainless steel used for food related things is aquarium safe.
Tie a string to the spoon and keep it outside the tank. Then you can pull the spoon up without putting your arm in the water.
Magnets used in aquariums are usually covered, for example, in plastic dip. However, the magnet used in filter impellers is bare. I wonder how much contact they have with the water?

Magnets are iron, there's no copper. A lot of magnets use other metals as an alloy (e.g., Neodymium) , but copper is not generally used.

I assume you're using a magnetic clip or something? The magnet should be reasonably sealed.

I was going to put a piece of zucchini or cucumber between two to weigh it down in order ti feed my rabbit snail. I ended up using attaching the veggie to a clear glass bead via a rubber band... works like a charm and the snail loves cucumber especially.
