How does a linear motor work?

Used in many industrial and (high-tech) fabrication applications, linear motors are an invaluable part of the fastest and most efficient processes. But how do linear motors work? This video explains the basic electrical principle of linear motion.
We will start by looking at the difference between a traditional motor, and a linear motor, and then we will show how a linear motor works using some basic concepts.
By the end of this video, you will be able to understand how a linear motor works, how it can be used in a variety of applications, and why it is so common in everyday life.

I think it is a linear synchronous motor.
