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
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 magnet is made of any of a group of metals called ferromagnetic metals. Ferromagnetic metals contain many small magnetic fields called domains. In their natural state, the magnetic fields of these domains point in different directions. To create a magnet, the magnetic fields must align in the same direction.Full Answer >
The magnetic field lines of a magnet run from north to south, according to HowStuffWorks. The force leaves the north pole and enters the south pole of another magnet, which creates a closed loop. Magnets attract each other when their lines of force are running in the same direction, and they repel each other when their lines of force travel in opposite directions.Full Answer >
Based on magnetic properties, there are three major types of magnets: permanent, temporary and electromagnets. Permanent magnets retain their magnetism once magnetized while temporary magnets only exhibit magnetic properties whenever they come within range of a magnetic field, and only for a short period. Electromagnets are magnets that only display magnetic properties when current passes through their core.Full Answer >
