Earth's Magnetic Field

Universe

The totality of space, time, matter, and energy that encompasses all celestial bodies, galaxies, and cosmic phenomena.

Earth

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

Sun

The star at the center of the Solar System, providing light and heat that sustain life on Earth.

Milky Way Galaxy

The galaxy that contains our Solar System, characterized by its spiral shape and composed of billions of stars, including the Sun.

Solar System

The gravitationally bound system comprising the Sun and all objects that orbit it, including planets, moons, asteroids, and comets.

Solar Neighborhood

The region of space surrounding the Solar System, typically defined as the area within a few dozen light-years that contains nearby stars and stellar systems.

Magnetosphere

The region around a planet dominated by its magnetic field, which protects 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 electrostatic forces.

Magnet

An object that produces a magnetic field, attracting ferromagnetic materials like iron, nickel, and cobalt.

Dipolar

referring to a magnetic field with two poles, north and south, that exhibit opposite magnetic properties.

Magnetism

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

Magnetic field lines

Imaginary lines that represent the direction and strength of a magnetic field, indicating the path a north pole would follow in the field.

Iron fillings

small pieces of iron used to visualize magnetic fields by aligning along magnetic field lines.

Electromagnet

A type of magnet in which the magnetic field is produced by the flow of electric current, typically consisting of a coil of wire with an iron core.

Electric current

The flow of electric charge, typically measured in amperes, which generates a magnetic field when passed through a conductor.

Electromagnetic

relating to the interaction between electric fields and magnetic fields, often used in the context of waves or forces.
