What is a Magnetron? A magnetron is a device that uses the interaction of a stream of electrons, guided by a magnetic field, with cavities within a block of copper to produce microwave radiation. The frequency range of the radiation depends on the size of the cavities.

Magnetosphere A rendering of the magnetic field lines of Earth's magnetosphere. A magnetosphere is the region of space surrounding an astronomical object in which charged particles are controlled by that object's magnetic field.Near the surface of many astronomical objects, the magnetic field resembles that of a dipole.tudy of Earth's magnetosphere began in 1600, when William Gilbert discovered that the magnetic field on the surface of Earth resembled that on a terrella, a small, magnetized sphere.

Magnet Manufacturing Process Therefore, these magnets are most often called sintered magnets. Ferrite, Samarium Cobalt (SmCo) and neodymium-iron-boron (neo) magnets are all made by this method. Unlike ferrite, which is a ceramic material, all of the rare earth magnets are metal alloys.How SmCo and Neo Magnets are MadeSuitable raw materials are melted under vacuum or inert gas in an induction melting furnace.errite, Samarium Cobalt (SmCo) and neodymium-iron-boron (neo) magnets are all made by this method.

Cyclotron The cyclotron was one of the earliest types of particle accelerators, and is still used as the first stage of some large multi-stage particle accelerators. It makes use of the magnetic force on a moving charge to bend moving charges into a semicircular path between accelerations by an applied electric field.

Magnetite Magnetite is a mineral, one of the three common naturally occurring iron oxides (chemical formula Fe3O4) and a member of the spinel group. Magnetite is the most magnetic of all the naturally occurring minerals on Earth.Naturally magnetized pieces of magnetite, called lodestone, will attract small pieces of iron, and this was how ancient people first noticed the property of magnetism.agnetite is the most magnetic of all the naturally occurring minerals on Earth.

Think You Might Be in Labor? When to Go to the Hospital If you aren't given a specific time to go into the hospital by your doctor or midwife, consider using the 411 method: Contractions 4 minutes apart, lasting 1 minute, for at least 1 hour. The cramping may begin in your upper and lower abdomen and/or back.

- Magnetic resonance imaging (MRI), nuclear magnetic resonance imaging (NMRI), or magnetic resonance tomography (MRT) is a medical imaging technique used in radiology to investigate the anatomy and physiology of the body in both health and disease.he very high strength of the magnetic field can cause projectile effect (or missile-effect) accidents, where ferromagnetic objects are attracted to the center of the magnet. Pennsylvania reported 27 cases of objects becoming projectiles in the MRI environment between 2004 and 2008.

Magnetic Resonance Imaging (MRI) What is magnetic resonance imaging (MRI)? Magnetic resonance imaging (MRI) is a scanning procedure that uses strong magnets and radiofrequency pulses to generate signals from the body. These signals are detected by a radio antenna and processed by a computer to create images (or pictures) of the inside of your body.

Is Cloud Seeding a Health Risk? Boron (IPA: /ˈbɔːrɒn/) is a chemical element with atomic number 5 and the chemical symbol B. A trivalent compound containing boron occurs abundantly in the ore borax. Boron is never found free in nature, and is a non-metal. Several allotropes of boron exist; amorphous boron is a brown powder, though crystalline boron is black, hard (9.3 on Mohs' scale), and a weak conductor at room temperature.

Hadron A hadron, in particle physics, is any subatomic (smaller than the atom) particle or antiparticle which is made of quarks. Quarks are fundamental particles which among other properties have an electrical charge and a name (e.g. 'up', 'down', 'strange'). The electrical charge of a single quark is always a fraction (e.g. 2/3).

- Sponsored Links. Magnets are objects that produce an area of magnetic force called a magnetic field. Magnetic fields by themselves are invisible to the human eye. Iron filings can be used to show magnetic fields created by magnets (such as in the picture to the right).

Spine MRI Magnetic resonance imaging (MRI) of the spine is a noninvasive procedure that uses powerful magnets and radio waves to create pictures of the spine area, including the spine bones (vertebrae), the spinal cord, and the spaces between the vertebrae through which the nerves travel. See also: MRI.

- MAGNETOSPHERE. The magnetosphere is the region that surrounds a planet and the magnetic field of that planet, in which charged particles are trapped and controlled by that planet’s magnetic field, rather than the solar magnetic field.lasmasphere: a region inside the magnetosphere which captures plasma that flows from the ionosphere, so that there is a plasma build-up. Pole: an extremity of an axis through a sphere; in a magnet, one of two places where it is most intense; the two poles have opposite charges (+/-).

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.

What is a Magnet? Air-core magnets are created by current flowing through a wire. That current produces the magnetic field. You create an air-core magnet by wrapping miles of wire around in a doughnut shape (toroid). When you send current through the wire, a magnetic field is created inside of the doughnut.

Magnetometers Magnetometers are devices that measure magnetic fields. A magnetometer is an instrument with a sensor that measures magnetic flux density B (in units of Tesla or As/ m2). Magnetometers refer to sensors used for sensing magnetic fields OR to systems which measure magnetic field using one or more sensors.Since magnetic flux density in air is directly proportional to magnetic field strength, a magnetometer is capable of detecting fluctuations in the Earth's field.n example is a fluxgate magnetometer that can measure the strength of any component of the Earth’s field by orienting the sensor in the direction of the desired component. • Scalar magnetometers that measure only the magnitude of the vector passing through the sensor regardless of the direction.

Magnet Manufacturing Process Magnet Manufacturing Process. There are several processes for making magnets, but the most common method is called Powder Metallurgy. In this process, a suitable composition is pulverized into fine powder, compacted and heated to cause densification via “liquid phase sintering”. Therefore, these magnets are most often called sintered magnets. Ferrite, Samarium Cobalt (SmCo) and neodymium-iron-boron (neo) magnets are all made by this method. Unlike ferrite, which is a ceramic material, all of the rare earth magnets are metal alloys. How SmCo and Neo Magnets are MadeSuitable raw materials are melted under vacuum or inert gas in an induction melting furnace.
