Magnet A magnet is a very special metal. When a magnet goes near a special kind of metal or other magnets, and the poles (sides) touching are opposite, it will pull, or attract the other metal or magnet closer. Also, if the two poles are the same, the two magnets will push away, or repel, from each other. This is called magnetism.

Definitions &Translations This magnetic field is invisible but is responsible for the most notable property of a magnet: a force that pulls on other ferromagnetic materials, such as iron, and attracts or repels other magnets. A permanent magnet is an object made from a material that is magnetized and creates its own persistent magnetic field. An everyday example is a refrigerator magnet used to hold notes on a refrigerator door.

- All Rights Reserved. magnet a material that attracts steel, iron, cobalt, and nickel Magnets come in many shapes and sizes. Materials that contain iron, steel, nickel, and cobalt are attracted to, or pulled toward, a magnet. Magnets also attract the mineral magnetite and other magnets. Materials that are attracted to a magnet are described as magnetic.magnetite a mineral that is naturally magnetic Magnetite contains iron and is a weak magnet. Early explorers used magnetite to ﬁ nd north.

MAGNETISM FIND OUT MORE. Magnetism is what gives magnets their ability to attract objects made of iron or steel. A magnet creates around itself a region of space with special properties. This region is known as a MAGNETIC FIELD. When two magnets come near each other, their fields create forces that attract or repel. The Earth is itself a huge magnet, and the force its field exerts on other magnets makes them point in a north–south direction. This effect is used in the magnetic compass.

Magnetism Magnetism is a class of physical phenomena that are mediated by magnetic fields. Electric currents and the magnetic moments of elementary particles give rise to a magnetic field, which acts on other currents and magnetic moments.ecause this is a cross product, the force is perpendicular to both the motion of the particle and the magnetic field. It follows that the magnetic force does no work on the particle; it may change the direction of the particle's movement, but it cannot cause it to speed up or slow down.

All About Magnets Science All magnets have the ability to attract other magnets or magnetic objects (such as iron and some other metal objects). But a magnet doesn't necessarily have to touch a magnetic object for the object to be attracted to it. Try this experiment to learn why.

Magnet A permanent magnet is an object made from a material that is magnetized and creates its own persistent magnetic field.ften, the coil is wrapped around a core of soft ferromagnetic material such as steel, which greatly enhances the magnetic field produced by the coil. The overall strength of a magnet is measured by its magnetic moment or, alternatively, the total magnetic flux it produces.

- Magnetite is a mineral and one of the main iron ores. With the chemical formula Fe 3 O 4, it is one of the oxides of iron. Magnetite is ferrimagnetic; it is attracted to a magnet and can be magnetized to become a permanent magnet itself. It is the most magnetic of all the naturally-occurring minerals on Earth.

Magnet An electromagnet is made from a coil of wire that acts as a magnet when an electric current passes through it but stops being a magnet when the current stops. Often, the coil is wrapped around a core of soft ferromagnetic material such as steel, which greatly enhances the magnetic field produced by the coil.The overall strength of a magnet is measured by its magnetic moment or, alternatively, the total magnetic flux it produces.aterials that can be magnetized, which are also the ones that are strongly attracted to a magnet, are called ferromagnetic (or ferrimagnetic). These include iron, nickel, cobalt, some alloys of rare earth metals, and some naturally occurring minerals such as lodestone.

Biography Born in New York City to legendary screen star Henry Fonda and New York socialite Frances Seymour Brokaw, Jane Seymour Fonda was destined early to an uncommon and influential life in the limelight. Although she initially showed little inclination to follow her father's trade, she was prompted by Joshua Logan to appear with her father in the 1954 Omaha Community Theatre production of The Country Girl.

Magnetic force A magnet is an object that has a magnetic force. Magnetic force exists around a magnet or electrical field. An electric field is a space surrounding an electric charge. We can say, therefore, that magnetic force is generated electromagnetically. Permanent magnets are also known as ferro-magnets.

What Is Magnetism? What is magnetism? A: Magnetism is a phenomenon of physical science that arises due to the forces between objects brought about by the motion of electrical charges within those objects. The motion of electric charges creates a magnetic field, which exerts a magnetic force on charged particles that move within that field.
