Our planet’s magnetic field, a robust and intriguing characteristic, behaves like a colossal, unseeable barrier safeguarding us from harmful solar radiation. It originates deep within the Earth’s core where the spinning molten iron generates a magnetic effect.

2023年10月16日 · The Earth’s magnetic field is the magnetic field that surrounds the Earth. It is sometimes called the geomagnetic field. The Earth’s magnetic field is created by the rotation of the Earth and Earth's core. It shields the Earth against harmful particles in space. The field is unstable and has changed often in the history of the Earth.

Perhaps the most important feature of the Earth's magnetic field is that it protects us from the Sun's solar wind and radiation. The Electric Magnet and Motor Magnets can also be created by using electricity.

Earth's magnetic field protects us from the sun's radiation. The North and South poles have natural colorful light shows called northern and southern lights. These lights are caused by sprays of energy coming off the sun bumping into the magnetic field of Earth.

The Earth’s Magnetic Field. The Earth’s core is apparently a mix of iron and nickel, which of course gives the Earth it’s very own magnetic field. The effect of Earth’s magnetism extends nearly 60,000km out into space. That’s seriously far!

The planet Earth is a giant magnet. Because the south pole of a compass is attracted to the north pole of Earth, the compass needle always points north. Today magnets are found in many places.

2023年9月14日 · A magnet creates an invisible area of magnetism all around it called a magnetic field. The north pole of a magnet points roughly toward Earth's north pole and vice-versa. That's because Earth itself contains magnetic materials and behaves like a gigantic magnet.

The Earth has a magnetic field surrounding it with properties much like those of the area surrounding a bar magnet. The photo below shows iron filings tracing out the bar magnet’s lines of the magnetic force.
