HOW DO MAGNETS WORK?


Magnets have an invisible field that forces other objects to react to its properties. This powerful force is called the magnetic field.
Magnetic fields have particles called electrons that actively shift and move within the field. These electrons continuously revolve around the core of the magnet (its poles), creating energy that attracts objects. Because of this, magnets have the ability to draw objects towards itself. This ability is called magnetism, caused by the force field that magnets create through its electrons (negative charge) and protons (positive charge).
If two magnets are close together, try figuring out which ends tend to meet. If you look closely, you’ll see that unlike poles attract each other, while identical poles repel each other. If you place the south pole of a magnet beside the north pole of another magnet, they will stick together. On the other hand, putting two magnets with both north poles facing each other will force them apart.
