Pendulum experiments and the fundamental laws of electrodynamics

We utilize a more rigorous way to calculate the radiated electromagnetic energy and field momentum in electromagnetic impulse pendulum experiments previously carried out by various authors. We consider the impulse pendulum and the rest of the circuit as a magnetic dipole. Calculating the previous authors´ wrongly defined vacuum reaction force F_vac we prove that this force is not equal to the Lorentz force F_L as they stated. Specifically, we prove that F_vac arising from the whole loop is always equal to zero. We also prove that the field momentum P_field arising from the whole loop is always equal to zero. In addition we show that the momentum imparted to the impulse pendulum is not equal to P_field as they claim, and that the field energy radiated by the impulse pendulum is not equal to (mv)c, where mv is the momentum of the pendulum. Therefore, we have proven that the previous analysis is incorrect and not physically valid
