Magnetism
Magnetism starts with a simple idea: some materials create fields that can attract, repel, and push on moving charges. From bar magnets to electromagnets, the same core rules explain everyday objects, laboratory experiments, and many modern technologies. This topic hub helps you move from a first visual overview to interactive field exploration and hands-on investigation.

Common Questions
What is magnetism in simple terms?
Magnetism is a force caused by magnetic fields. It can attract or repel magnets and can also affect certain materials and moving electric charges.
What is the difference between a magnet and an electromagnet?
A permanent magnet keeps its magnetic field on its own, while an electromagnet creates magnetism when electric current flows through a coil of wire.
