Electromagnetic Induction - Electricity and Magnetism are two different aspects of the same underlying phenomenon, i. If the separation of the two coils increase, the less magnetic field reaches another coil and less mutual inductance. – A free PowerPoint PPT presentation (displayed as a Flash slide show) on PowerShow. How to deal with Leakage Elements in Flyback Converters Prepared by: Christophe Basso ON Semiconductor Introduction It is difficult to find a good tradeoff between cost and performance when designing offline Flyback power supplies. This depends on the geometrical properties of the coils, such as the number of turns and radii of the turns of. The constant M, called the mutual inductance of the two circuits, is dependent on the geometrical arrangement of both circuits.
