It is likely one of the 4 elementary forces of nature, together with gravity, the weak power, and the sturdy power. Magnetic forces are accountable for the attraction or repulsion between magnets and magnetic supplies.
Metals are supplies which might be good conductors of electrical energy and warmth. They’re sometimes shiny and have a excessive density. Metals could be magnetized by exposing them to a magnetic area. The power of the magnetization depends upon the kind of metallic, the power of the magnetic area, and the temperature of the metallic.
