Forces need contact
Forces need contact between two objects. Imagine a football, when you kick it changes direction. It won't change direction on its own until it hits something. Imagine dropping a book. It won't stop until it hits the floor. It needs contact before it changes.
Magnetic forces are forces that a made using a magnet. These don't need to touch objects for it to cause a force, the magnet can either push or pull using a magnetic force.
When two magnets are close, they create pushing or pulling forces on one another. Watch the video to find out about North & South poles
