Abstract It is known that Lorentz Force and Ampere force contradicts the Third Newton Law, but it does not contradict the more general Law of Momentum Conservation, as the electromagnetic field has a momentum. From this it follows that the Lorentz and Ampere forces must be balanced by the flow of electromagnetic momentum. However, as far as the author knows, there is no corresponding quantitative comparison and therefore it is discussed below. In particular, it is shown that some of the corollaries of the Momentum Conservation Law can be found. Content 1. Introduction2. The Field’s Configuration3. The Lorentz Force4. The Ampere Force5.

Introduction It is known that Ampere force contradicts the Third Newton Law, but it does not contradict the more general Law of Momentum Conservation, as the electromagnetic field has a momentum. It is important to note that a stationary electromagnetic field can also have a momentum and therefore the Ampere force does not contradict law of conservation of momentum, also in the case when it occurs in conjunction with a permanent magnetic field. From this it follows that the Ampere force must be balanced by the flow of electromagnetic
