Does an electric can opener attract to magnets?

Yes. In some cases, a magnet is a very useful tool to use with a can opener, because Without the magnet, the cut open can lid can fall into the can and it's difficult to get it out. With the magnet, once the can lid is cut open, it sticks to the magnet and does not fall into the can. Without the magnet, it's probably better to only cut open the can lid about 90% percent and pull the remaining part back, so it does not fall into the open can.
