Understanding What Magnetism Is
Magnetism is a force that can attract or repel certain materials, like iron or steel. This force comes from the movement of electric charges inside objects.
How Magnetism Works
Inside every magnet, tiny particles called electrons move and create magnetic fields. When many of these movements line up, the object becomes a magnet.
Magnetic Poles
Every magnet has two poles: north and south. Opposite poles attract each other, while the same poles repel. This is why magnets snap together in specific ways.
Where We See Magnetism
Magnetism appears in everyday tools like fridge magnets, speakers, compasses, electric motors, and even Earth itself, which acts like a giant magnet.
Magnetism in Nature
Earth’s magnetic field protects the planet from harmful solar radiation. Some animals, like birds and sea turtles, even use magnetism to navigate.
Why Magnetism Matters
Magnetism powers many technologies, from generators and motors to data storage and medical devices. It plays a key role in modern science and engineering.
The Simple Takeaway
Magnetism is a natural force created by moving electric charges. It attracts or repels materials and is essential in both nature and technology.
