Explanation:

Match the terms on the left with their correct definitions on the right based on knowledge of magnet - related concepts in physics. Magnetic domain is a group of atoms with their magnetic poles pointed the same direction. Magnetic field is imaginary lines of force around a magnet. Magnetism is a force created through a magnetic field. A compass is a magnetic needle that is free to turn. An electromagnet is a current - carrying wire wrapped around an iron core. An electric generator is a device that uses induction to produce electric power. An aurora is colored lights in the sky created by the interaction of Earth’s magnetic field and charged particles in the solar wind. The magnetosphere is the magnetic field around Earth that extends into space.
