Metals that are attracted to magnets include iron, nickel and cobalt. The majority of metals are not attracted to magnets, including copper, silver, gold, magnesium, platinum and aluminum. However, the metals that are not attracted to magnets may magnetize slightly when placed in a magnetic field.Know More
Magnetic fields cannot be seen by the naked eye. Materials, such as wood, plastics and glass, are not attracted to magnets. Magnetism is capable of either pulling objects in or pushing them away. Magnets have a north and a south pole. When the same poles of two magnets are near, they push away from each other. When there are two different magnet poles in close proximity, they pull towards each other. It is necessary for magnetic objects to be securely within a magnetic field for responsiveness, explaining why an object sometimes needs to be moved a little closer in order for magnetism to affect an object noticeably.
Scientists claim that Earth's core consists of a combination of iron and nickel, with the planet having its own magnetic field. Earth's magnetic field protects the planet from harmful solar wind through deflection. Compasses that are magnetic utilize Earth's magnetic field to facilitate navigation in different directions.Learn more about Magnetism
All magnets have both a north and a south pole, which causes them to either repel or attract one another depending on how the two poles are lined up. If the north pole of one magnet meets the south pole of another, the two will be attracted, but if either both north or south poles meet, the magnets will repel one another.Full Answer >
Magnets attract when two opposing poles are brought together and repel when they have similar poles. Magnets come with a north pole and south pole. If one end of a magnet is the north pole and the end of the other magnet is the south pole, both pieces will attract; magnets will repel if two north poles or south poles are brought together.Full Answer >
Magnets are used in computer data storage, compasses, doorbells and alarm systems, microphones and speakers, motors, electrical generators and electrical transformers. They are also used to levitate objects, including trains that operate via magnetic propulsion. Naturally occurring magnetism protects the Earth from cosmic radiation.Full Answer >
One example of a magnet is a refrigerator magnet. These are also called permanent magnets because they always retain a certain degree of their magnetism. There some other general categories for magnets, such as temporary magnets and electromagnets.Full Answer >
