Linear Motor

Imagine you have a toy car that moves forward or backward when you push it. That's kind of like how a linear motor works, but instead of using wheels, it uses magnetic fields to propel an object.

So, a linear motor is made up of two parts: a stationary (not moving) portion, and a moving portion, which is sometimes called the "slider." The stationary portion has coils of wire (kind of like a bunch of rubber bands twisted together) that are charged with electricity, creating a magnetic field. The slider has powerful magnets attached to it, which are attracted to the stationary coils.

When the electricity flows through the coils, it creates a magnetic field that pushes the slider along – almost like magic! The slider can move back and forth along the stationary portion, and the faster the electricity flows through the coils, the faster the slider will move.

Some common examples of linear motors include things like roller coasters, where the cars are propelled along the track by linear motors in the track itself. Linear motors are also used in trains, where the magnetic forces push the train forward without using any physical contact between the train and the track. It's like having superpowers to move things without touching them!
