Human magnetism

People alleged to have such an ability are often called human magnets.

Although metal objects are the most prevalent material of attraction, some "human magnets" are also able to stick other types of materials to their skin, such as glass, porcelain, wood or plastic as well as metals with no ferromagnetic properties, such as brass and aluminium.

That would suggest that the phenomenon cannot be explained by magnetism and uses a different kind of physical effect.

He also noted that those people usually have smooth and hairless skin and lean back slightly while sticking objects, which would not be necessary if they possessed magnetic powers.

Many scientists and proponents of science, including James Randi, have explained this ability by friction and sticky skin; to prove that, Randi has demonstrated that human magnets lose their powers when they are covered in talc.
