H Bridge Motor Control Basics Explained

The video tutorial explains the principles of magnetism, including attraction and repulsion, and how an electromagnetic field is created by current flowing through a coil. It covers reversing polarity by changing current direction and controlling magnetic fields. The tutorial also discusses using magnets and coils for precise rotation, and controlling this with an H bridge and electronic switches. Finally, it explains how the frequency of switching affects control.
