Fridge Magnet

Why do fridge magnets hold their own weight and more without a power source?

Everything that does work must have a power source. Magnets certainly do perform work, but science cannot explain a power source for them.
The fridge magnet is definitely doing work because it’s resisting the pull of gravity, which is a work being done too.
Without a power source, how can a magnet do that work?

work = force x distance
power = work / time

A magnet sticking to a refrigerator is not moving and so is doing no work. Hence, no power is required. In the same way, when a heavy block is sitting on a table, the table exerts a force but since the block isn’t moving, the table doesn’t need a power source.

As for why the refrigerator magnet doesn’t just slide down under the influence of gravity, the answer is friction – in particular, the coefficient of static friction.
