Magnetosphere Protects The Earth

Earth’s magnetic field dominates a region called the magnetosphere, which wraps around the planet & its atmosphere. Solar wind, charged particles from the sun, presses the magnetosphere against the Earth on the side facing the sun & stretches it into a teardrop shape on the shadow side.magnet fishing square magnets The magnetosphere protects the Earth ….  Read More

Geomagnetic Poles

Geomagnetic Poles The Earth is a magnet. Scientists do not fully understand why, but they think the movement of molten metal in the Earth’s outer core generates electric currents. The currents create a magnetic field with invisible lines of force flowing between the Earth’s magnetic polesbig ring magnet. The geomagnetic poles are not the same ….  Read More

magnets have north & south poles

Magnetism is the force exerted by magnets when they attract or repel each other. Magnetism is caused by the motion of electric charges. neodymium bar Every substance is made up of tiny units called atoms. Each atom has electrons, particles that carry electric charges. Spinning like tops, the electrons circle the nucleus, or core, of ….  Read More
