Earth's Magnetic Field

Universe

The vast expanse that includes all of space, time, matter, and energy. It encompasses galaxies, stars, planets, and all forms of radiation and particles.

Earth

The third planet from the Sun, known for its ability to support life, characterized by its atmosphere, water, and suitable temperatures.

Sun

The star at the center of the Solar System, providing light and heat necessary for life on Earth. It is a nearly perfect sphere of hot plasma and is the most important source of energy for our planet.

Milky Way Galaxy

The galaxy that contains our Solar System, characterized by its spiral shape and comprising billions of stars, gas, and dust.

Solar System

The gravitationally bound system of the Sun and the objects that orbit it, including eight planets, their moons, dwarf planets, asteroids, and comets.

Solar Neighborhood

The region of space surrounding the Solar System, containing nearby stars and stellar systems, typically within a few parsecs.

Magnetosphere

The region around a planet dominated by its magnetic field, protecting it from solar wind and cosmic radiation.

Non Contact force

A force that acts at a distance, without physical contact, such as gravitational, magnetic, or electric forces.

Magnet

An object that produces a magnetic field, attracting ferromagnetic materials and influencing other magnets.

Dipolar

referring to a magnetic field with two poles, north and south, where field lines emerge from the north and enter the south.

Magnetism

The physical phenomenon produced by the motion of electric charge, resulting in attractive and repulsive forces between objects.

Magnetic Field Lines

Imaginary lines that represent the direction and strength of a magnetic field, emerging from the north pole and entering the south pole.

Iron Fillings

small metallic particles used to visualize magnetic fields, aligning along magnetic field lines.

Electromagnet

A type of magnet in which the magnetic field is produced by an electric current. Electromagnets can be turned on and off and are commonly used in various applications such as motors and generators.

Electric Current

The flow of electric charge, typically measured in amperes, which can generate a magnetic field when passing through a conductor.

Electromagnetic

relating to the interaction of electric currents or fields and magnetic fields.
