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
Magnets have a north and south pole, and bringing two like poles together repels magnets while unlike poles attract each other. The distance in which two magnets begin to repel or attract each other is determined by the strength of the magnetic field.Full Answer >
Magnets have been known since antiquity and occur naturally through a mineral known as magnetite. Magnetite is an iron oxide and contains a high concentration of iron, which magnetizes when it forms. This mineral is also known as lodestone.Full Answer >
A temporary magnet is a magnet that stays magnetized only for a relatively short period of time. Non- electromagnetic temporary magnets tend to be made of soft magnetic materials, like annealed iron or steel.Full Answer >
Magnets that can be made easily from material found at home are called homemade magnets. These are very small and weak magnets. They are primarily for having fun and teaching children about magnetism.Full Answer >
