Ferromagnetic materials have the ability to form and grasp a specific arrangement of positive or negative atoms. When the positive end of one magnet meets the negative end of another, the two metals adhere together through this bond.

Factors such as heat and extreme pressure weaken their power of attraction. Electromagnets use electricity in the form of coils to generate a magnetic field around a conductive metal so they are capable of being turned on and off.
