Glossary of Magnet Terms A keeper is a piece (or pieces) of soft iron that is placed on or between the pole faces of a permanent magnet to decrease the reluctance of the air gap and thereby reduce the flux leakage from the magnet. It also makes the magnet less susceptible to demagnetizing influences.

- 1 A magnet has two ends called poles, one of which is called a north pole or north-seeking pole, while the other is called a south pole or south-seeking pole. 2  The north pole of one magnet attracts the south pole of a second magnet, while the north pole of one magnet repels the other magnet's north pole.

- Magnets are made by exposing ferromagnetic metals like iron and nickel to magnetic fields. When these metals are heated to a certain temperature, they become permanently magnetized. It's also possible to temporarily magnetize them by using a variety of methods you can try safely at home.

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.

What is a Magnet? A magnet is an object or a device that gives off an external magnetic field. Basically, it applies a force over a distance on other magnets, electrical currents, beams of charge, circuits, or magnetic materials. Magnetism can even be caused by electrical currents. While you might think of metal magnets such as the ones you use in class, there are many different types of magnetic materials. Iron (Fe) is an easy material to use. Other elements such as neodymium (Nd) and samarium (Sm) are also used in magnets.

- Magnetism is the phenomenon associated with the motion of electric charges, although the study of magnets was very confused before the 19th century because of the existence of ferromagnets, substances such as iron bar magnets which maintain a magnetic field where no obvious electric current is present (see below).

- Some facts about magnets include: 1  the north pole of the magnet points to the geomagnetic north pole (a south magnetic pole) located in Canada above the Arctic Circle. 2  north poles repel north poles. 3  south poles repel south poles.4  north poles attract south poles.5  south poles attract north poles. magnet is any material or object that produces a magnetic field. This magnetic field is responsible for the property of a magnet: a force that pulls on other ferromagnetic materials and attracts or repels other magnets.

- 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.

INTRODUCTION What is a magnet? A magnet is an object made of certain materials which create a magnetic field. Every magnet has at least one north pole and one south pole. By convention, we say that the magnetic field lines leave the North end of a magnet and enter the South end of a magnet. This is an example of a magnetic dipole (di means two, thus two poles). If you take a bar magnet and break it into two pieces, each piece will again have a North pole and a South pole.

Magnet school In the U.S. education system, magnet schools are public schools with specialized courses or curricula. Magnet refers to how the schools draw students from across the normal boundaries defined by authorities (usually school boards) as school zones that feed into certain schools. There are magnet schools at the elementary, middle, and high school levels.
