(Quote from SWAT_OP-R8R) Because the word magnetic is rather vague, you have 3 type of magnetic effect: diamagneticparamagneticferromagnetic (Some materials, such as mu-metal has the property of having a magnetic permeability) Diamagnetic objects, ie, which magnetize in the opposite direction of the magnetic field in which they are placed. Levitation can be obtained when the magnetic force that applies to the diamagnetic object exactly compensates for the weight of the latter. It requires very …

(Quote from LordRaydenMK) Humm, the atom have an expiry date, be careful not to exceed the deadline Nuclear Reactions The strong interaction maintains the cohesion of the nucleons within the nucleus. It is the most intense of the four fundamental forces of nature (hence its name). It is characterized by the fact that it is strongly attractive at short distance (when the nucleons approach very close to one another), repulsive at "medium" distance, and vanishes at long distances. Since protons ar…
