Question

i was with my grand mother going to hazel del washington and i thot about that so how do thay stick to medal

ok how dose it work iv got a magnet and it sticks to things without glue i want to know how it works

Answer 1

Magnets exert a force on certain metals only - iron, plain steel, nickel, and cobalt being the main ones. There are also a few metal alloys like alnico (aluminum+nickel+cobalt) that can be made into magnets. Good quality stainless steel is not attracted to magnets very much, but poor quality SS is. (This is because in good quality SS, the atoms and electrons are almost fully lined up and tied up in the atomic bonds.)

A magnet will not attract copper, yet copper (or any other metal) can be made into a magnet by the passage of electricity through it - making an "electromagnet". This is how electric motors function.

Answer 2

When a magnet is brought close to another magnet or to magnetizable metal, the magnetic field becomes more concentrated due to the interaction with the individual magnetic fields of the atoms of the material. This concentration has lower potential than the expanded field and energy is available as force, drawing the magnet closer, which increases the concentration, etc. When you pull them apart, you are adding energy.

Answer 3

because it something happens at an atomic level, the negative charges repel the others. all mass is mostly space. the only reason why your feet doesn't fall through the space is because the electrons repel. if a nucleus was the size of a tennis ball, the first electrons would be 1 mile away.
