At first, I regard magnetism. I can show that the magnetic force is an electric angle-effect by establishing two postulates: the dependence of the electric force on the velocity, and the existence of the anti-field. With the help of a third postulate, this is the quantization of the energy-transfer of the electric field, I then show that gravitation is also an electric effect. So, the three postulates describe three qualities of the electric field by which magnetism and gravitation can be derived. I finally carry out quantum-mechanical considerations at which the three postulates will be excellently confirmed. For the correct classification of this work I must mention that the theory of special relativity is absolutely considered as being correct and that it is an important and necessary component of this work.
