Swarm consists of three satellites that work in unison to measure the magnetic field. Today ESA's Swarm-mission have taken over after Ørsted and provides even more precise Eeath magnetic field data. Developed by scientists at DTU Space in close cooperation with NASA, the models are used all over the world to search for oil and minerals. The satellite sends measurements of the Earth’s magnetic field to scientists, who use these data to devise advanced models of the Earth’s magnetic field. At the moment, the Earth’s magnetic field is decreasing by approximately 5 percent per century, and scientists are unable to explain the reason for this or describe the consequences this will have.ĭTU Space was heavily involved Danish Ørsted satellite project that ended in 2013. In the magnetic field, other objects can be drawn to the magnet.Scientists are studying the magnetic field to learn more about the Earth’s core, where the field is generated, and to determine how constant variations in the magnetic field affect life on Earth. Learn More All About Magnetism and How It Works Around magnet poles is an area known as a magnetic field. The arrow always points to the North Pole. A collapsed star, known as a neutron star, has the strongest magnetic force of any object in the universe.The magnets on your refrigerator have more magnetic force. The Earth’s magnetic force is not very strong.Its North and South poles are highly magnetic. Magnet Attracts metals like iron or steel. In the magnetic field, other objects can be drawn to the magnet. Around these poles is an area known as a magnetic field.

These are the parts where the magnets are strongest. The two ends of a magnet are called the north and south poles. When something is magnetic, it can pull things with steel or iron in them to it.

All About Magnetism: The two ends of a magnet are called the north and south poles.

When the electrons all spin in the same direction, though, they create an invisible force known as magnetism. Most of the time, the electrons spin in random directions. Atoms have negatively charged electrons that spin around them. From your clothes to your desk, every bit of matter is made of tiny particles called atoms.
