How do linear motors work?

The primary and secondary parts of the motor interact through the use of iron cores. The primary part of the motor is the stattionary part, which contains coils wound around iron cores. When an electric current is applied to these coils, they create a magnetic field.

The secondary part of the motor is the moving part, which typically consists of a series of magnets arranged to create a magnetic field. When the primary part's magnetic field interacts with the magnetic field of the secondary part, it induces a force, causing the secondary part to move linearly.
