A magnet is an object that pulls certain metals toward itself, especially iron and steel. If you hold a magnet near a paper clip, the clip will jump toward the magnet and stick to it, even though you never touched them together. This pulling force is called magnetism.

Magnets have two ends called poles: a north pole and a south pole. Opposite poles attract each other (north pulls toward south), but matching poles push each other away. If you try to push two north poles together, you'll feel them repel each other, like invisible hands pushing back.

Magnets power countless useful things. Electric motors use magnets to spin, which means magnets help run everything from fans to electric cars. Computers store information using tiny magnets. Doctors use powerful magnets in MRI machines to see inside the human body without surgery. Compasses use magnets to point north, helping travelers navigate.

The Earth itself acts like a giant magnet, which is why compass needles always point the same direction. Some animals, like sea turtles and homing pigeons, can sense Earth's magnetic field to find their way across vast distances. Scientists don't fully understand how this works, but it shows that magnetism is woven throughout nature, not just into human inventions.
