Rare-earth magnet First developed in the 1970’s and 80’s, super magnets are the strongest type of permanent magnets ever made, are ferromagnetic, meaning that like iron they can be magnetized, and have Curie temperatures that are below room temperature.

Magnets and Magnetism Magnets and Magnetism. A magnet is a piece of rock or metal that can pull other metals towards it. The force of magnets is called magnetism. Together with gravity and electricity it is a basic force of nature. Early humans discovered magnets and magnetism thousands of years ago. They found out that certain types of rock, called loadstone, pulled iron and other metal objects towards it.

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.

Magnetic dipole magnetic dipole. 1  generally a tiny magnet of microscopic to subatomic dimensions, equivalent to a flow of electric charge around a loop. Electrons circulating around atomic nuclei, electrons spinning on their axes, and rotating positively charged atomic nuclei all are magnetic dipoles.

- 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.

magnet An object that attracts iron and some other materials. Magnets are said to generate a magnetic field around themselves. Every magnet has two poles, called the north and south poles. Magnetic poles exert forces on each other in such a way that like poles repel and unlike poles attract each other. A compass is a small magnet that is affected by the magnetic field of the Earth in such a way that it points to a magnetic pole of the Earth.

Magnetic levitation For the form of transportation, see Maglev. Magnetic levitation, maglev, or magnetic suspension is a method by which an object is suspended with no support other than magnetic fields. Magnetic force is used to counteract the effects of the gravitational acceleration and any other accelerations.

How Magnets Work Magnets are objects that produce magnetic fields and attract metals like iron, nickel and cobalt. The magnetic field's lines of force exit the magnet from its north pole and enter its south pole. Permanent or hard magnets create their own magnetic field all the time.

MAGNETISM Use a compass; north points to the south part of the magnet. Magnets (permanent) A magnet that keeps its magnetism for a long time (store magnet).Repels other magnets with the same polarity. It attracts opposite poles. It only attracts some metals. A magnet always has an even number of poles.

MRI (High-Field, Non-Claustrophobic) MRI (High-Field, Non-Claustrophobic) What is Magnetic Resonance Imaging (MRI)? Magnetic resonance imaging (MRI) is a technique that allows doctors to see inside the body in remarkable detail without using radiation. Instead, MRI uses a powerful magnet, radio waves, and a sophisticated computer system to produce pictures of various parts of the body. All Metro Imaging facilities feature high-field, non-claustrophobic MRI units.

Superconductivity A high-temperature superconductor levitating above a magnet. Superconductivity is a phenomenon of exactly zero electrical resistance and expulsion of magnetic fields occurring in certain materials when cooled below a characteristic critical temperature.It was discovered by Dutch physicist Heike Kamerlingh Onnes on April 8, 1911 in Leiden.n superconducting materials, the characteristics of superconductivity appear when the temperature T is lowered below a critical temperature Tc. The value of this critical temperature varies from material to material.

Rare-earth magnet Ferrofluid on glass, with a rare-earth magnet underneath Rare-earth magnets are strong permanent magnets made from alloys of rare-earth elements (elements in the lanthanide series, plus scandium and yttrium). Developed in the 1970s and 1980s, rare-earth magnets are the strongest type of permanent magnets made, producing significantly stronger magnetic fields than other types such as ferrite or alnico magnets.
