WebApr 21, 2015 · 5. As you may know, the friction is proportional to the normal force of an object or in this case the force of attraction between magnet and refrigerator. If your force is strong enough then the friction will be sufficient and the magnet will not slip (on earth the force of friction must exceed the mass of your magnet multiplied by 9.81 m/s). WebDec 13, 2024 · Magnets and electricity. Basics. The spinning of the electrons around the nucleus of an atom creates a tiny magnetic field. The electrons in most objects spin in random directions, and their magnetic forces cancel each other out. Magnets are different because the molecules in magnets are arranged so that their electrons spin in the same …

WebMagnetic fields exert forces on other moving charges. The force a magnetic field exerts on a charge q moving with velocity v is called the magnetic Lorentz force . It is given by. F = q v × B.
