Study of matter, energy, and their interactions in the universe.
A field is an invisible area that can push or pull objects. The most famous fields are gravity, electric, and magnetic fields.
Electricity and magnetism are two sides of the same coin! Moving electric charges create magnetic fields, and changing magnetic fields can make electricity flow.
The strength of a force in a field can be calculated, but the key is that fields explain how objects interact at a distance, without touching.
A compass needle points north thanks to Earth's magnetic field.
Electric generators use magnets and wires to produce electricity.
Fields describe invisible forces like gravity and electromagnetism that shape our world and technology.
