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.

What happens to opposite ends of magnets when they are brought close together?

How does wrapping a wire into a coil affect the electromagnetic field created by the current?

Explain how the polarity of a magnetic field can be reversed.

Describe the role of switches in controlling the rotation of the rotor in an electromagnetic system.

What is the effect of changing the frequency of switching on the rotor's movement?
