Atoms within all materials are made up of a balance of positive and negative charges which like to stick together. Positive elements are stored within the centre called protons; negative elements are stored in the electron which circles the atom.
Materials can be made unbalanced, either by decreasing or increasing the number of negative electrons within the material.
Materials can store useful electricity by holding a positive and negative charge separately. Other forms of energy can be created when re-joining the two charges back together.
Electricity can travel through any material but much more easily through metals.
Magnetism is created whenever electricity is moving. The theory of electromagnetism was mainly developed with the 19th century.
