I always heard that magnetic forces don't do work, and that they act perpendicularly to the direction of movement.

The metallic ball is attracted to the electromagnet because the magnet creates a magnetic field that induces a magnetic field in the ball. This interaction causes the ball to be pulled towards the magnet.
An electromagnet is different from a regular magnet because it is made by passing an electric current through a coil of wire wrapped around a core material, such as iron. This creates a temporary magnetic field, whereas a regular magnet has a permanent magnetic field.
The strength of the electromagnet affects the attraction to the metallic ball because the stronger the magnetic field, the more force it exerts on the ball. This force is what pulls the ball towards the magnet.
No, not all metals can be attracted to an electromagnet. Only metals that contain iron, nickel, or cobalt can be attracted to an electromagnet. This is because these metals have magnetic properties that allow them to be influenced by a magnetic field.
You can increase the magnetic attraction between the electromagnet and the metallic ball by increasing the strength of the magnetic field. This can be done by increasing the number of coils in the wire or by increasing the amount of current passing through the wire.
