Are there any types of food that have magnetic properties?
In terms of food presentation, I thought it would be spectacular to have it float or levitate above the table instead of being served on a plate. Hence I wonder whether there are any types of food that have magnetic properties. Or, put differently, I'm curious whether magnetic material exists that is (safely) edible.

The reason why the full word is "ferromagnetic" is that magnetic substances are typically made out of iron. Iron is not really edible - you can (and have to) consume it as a trace element, but the daily dose is a few milligrams. If you put enough magnetized iron in a dish to lift it visibly, you will damage a lot of your digestive tract eating it. And that's even before the question of how you are going to orient the magnet if you have dispersed the iron in your food as some kind of powder.
There are also other metals which can be magnetic, but they are even worse for eating than iron. If there is any kind of space-age material that is magnetic without being a metal compound (I'm not on the leading edge of material science and don't know if such a thing exists), it is practically certain that it is not a food.
Levitation for presentation purposes exists, but it is done by levitating the plate, or sometimes by hiding magnets within a larger food structure (typically in cake art).

Quick Answer about "Are there any types of food that have magnetic properties?"
Some examples of food with iron include dark green vegetables (like spinach), meats (especially red meat), and fortified cereals. Iron is also one of the three magnetic metals (other two being nickel and cobalt). That means it is attracted to a magnet.What items have magnetic properties?

What kind of cereal is magnetic?
Iron particles in viscous and pasty products like yogurt, cheese spread and desserts can be carried off after they have been captured. Hygienic magnetic filters have such powerful Neoflux\xae (neodymium) magnetic bars that they can remove the smallest iron particles from these products.What is magnetism in food?
The examples of ferromagnetic solids include Cobalt, Nickel, Chromium Oxide etc. And they have widespread industrial and every day uses.Is Our Food Magnetic?
