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.

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.

magnetism In its most general form, magnetism may be defined as a special type of the physical interactions that arise between moving electrically charged particles. The transfer of magnetic interaction, which forms a bond between spatially separated bodies, is accomplished by a special material carrier, the magnetic field.

Definitions &Translations Magnetic Poles. The points where the equipotential surfaces of the terrestrial field of force graze the earth's surface; the points toward which the north or south poles of the magnetic needle is attracted. Over a magnetic pole the magnetic needle tends to stand in a vertical position.

FLUX magnetosphere - the magnetic field of a planet; the volume around the planet in which charged particles are subject more to the planet's magnetic field than to the solar magnetic field. magnetic field, magnetic flux, flux - the lines of force surrounding a permanent magnet or a moving charged particle.

The Meissner effect This is a true Meissner levitation. Lead is a type I superconductor below a temperature of 7.2 K; in this picture, it was cooled at 4.2 K with liquid helium. Vortices cannot exist in lead, and only the concave shape of the superconductor gives the levitation stability and prevents the magnet from sliding on the side.

Magnetic levitation The two primary issues involved in magnetic levitation are lifting forces: providing an upward force sufficient to counteract gravity, and stability: ensuring that the system does not spontaneously slide or flip into a configuration where the lift is neutralized.

Magnetization In classical electromagnetism, magnetization (magnetisation in British English) or magnetic polarization is the vector field that expresses the density of permanent or induced magnetic dipole moments in a magnetic material.

Ferromagnetism is a kind of magnetism that is associated with iron, cobalt, nickel, and some alloys or compounds containing one or more of these elements. It also occurs in gadolinium and a few other rare-earth elements.

Glossary of physics A magnetic field is the magnetic effect of electric currents and magnetic materials. The magnetic field at any given point is specified by both a direction and a magnitude (or strength); as such it is a vector field. magnetic field is the magnetic effect of electric currents and magnetic materials.

Magnetic levitation Stable magnetic levitation can be achieved by measuring the position and speed of the object being levitated, and using a feedback loop which continuously adjusts one or more electromagnets to correct the object's motion, thus forming a servomechanism.

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.

MAGLEV The flying train. If a Maglev wants to use this force to levitate, it needs a strong magnetic field in its wagons. We could use normal magnets, but their magnetic power is limited.

Ferromagnetism Ferromagnetism is the basic mechanism by which certain materials form permanent magnets, or are attracted to magnets. In physics, several different types of magnetism are distinguished. Ferromagnetism is the strongest type: it is the only one that typically creates forces strong enough to be felt, and is responsible for the common phenomena of magnetism in magnets encountered in everyday life. Substances respond weakly to magnetic fields with three other types of magnetism, paramagnetism, diamag

- Diamagnetic Levitation. Many common materials such as water, wood, plants, animals, diamonds, fingers, etc. are usually considered to be non-magnetic but in fact, they are very weakly diamagnetic. Diamagnets repel, and are repelled by a strong magnetic field.

What is magnetism? A magnetic field is the result of the motion of a charged particle or charged particles, and this field is generated in no other way. Any time a charged particle moves, it creates a magnetic field around its path of travel.
