Johann W. Goethe said that the biggest secrets were the open ones. You look at them but you do not see them. The same is true with the electromagnetic field. It is known fact that after switching off an electromagnet, its magnetic energy will be returned back to the circuit, usually as a spark. What was missed is the fact that the magnetic energy performed work by attraction of an iron bar and didn’t consume itself. This work, minus heat losses inside the circuit, is free energy or over unity energy.

This book is dedicated to all scientists, researchers and enthusiasts, who for the last 150 years were seeking to improve the world by developing electromagnetic machines and who didn’t restrain their minds by existing laws of thermodynamics invented by preceding scientists who declared them as universal ones.

The goal of this book is to unlock the secrets of over unity and to teach people what is over unity and how it works. The reader will learn basic ideas of making new ultra efficient electric motors and generators and how to improve existing patents which use permanent magnets.

• Textbook of general conditions for over unity, asymmetry of action of forces,
  
• logic of time and space factors for over unity;
  
• Proofs that the first two laws of thermodynamics are not universal;
  
• Usage of electrostatic and magnetic shields;
  
• Balancing opposing forces of the drag caused by Lenz’s law;
  
• Minimization of the drag caused by mutual attraction of the magnet and iron;
  
• Usage of electromagnets and the Inductive Spike;
  
• Why a good over unity generator is a bad over unity motor?

Note that in this book there is not a detailed design of a specific machine (other than those of the US patents presented in the Appendix). The goal of this book was not to be a builders manual, rather, as an aid to understand the operation and principles of these machines.
