Magnetic fields are created by moving electric charges. Whenever charged particles such as electrons move through a conductor or orbit around an atom, they generate a magnetic field. Additionally, magnetic fields are also generated by the movement of liquid iron within Earth's outer core.

Do magnetic fields have the same shape?
No, magnetic fields can have various shapes depending on the configuration of the magnets or current-carrying conductors creating them. The shape of a magnetic field is influenced by the orientation and arrangement of the magnetic sources.
What causes an object to exhibit magnetism?
An object exhibits magnetism when its atoms have aligned magnetic fields, creating a magnetic force.
What is a group of atoms that has magnetic fields pointing in the same direction?
A group of atoms with magnetic fields pointing in the same direction is called a magnetic domain. These domains are regions within a material where the magnetic moments of atoms align parallel to each other, creating a net magnetic moment for the domain.
What is inside a magnet that gives it its magnetic properties?
Inside a magnet, there are tiny particles called atoms that have their own magnetic fields. These atoms align in the same direction, creating a magnetic field that gives the magnet its magnetic properties.
How does a vibrating electric charge produce an electromagnetic wave?
When an electric charge vibrates, it creates changing electric and magnetic fields. These changing fields propagate through space, creating electromagnetic waves. The oscillating electric field produces a magnetic field, and the changing magnetic field then produces an electric field, thus creating a self-sustaining wave.
