2. Neodymium magnet - Wikipedia

   en.wikipedia.org/wiki/Neodymium_magnet

   The neodymium atom can have a large magnetic dipole moment because it has 4 unpaired electrons in its electron structure [14] as opposed to (on average) 3 in iron. In a magnet it is the unpaired electrons, aligned so that their spin is in the same direction, which generate the magnetic field. This gives the Nd 2 Fe 14 B compound a high ...

3. Earth's magnetic field - Wikipedia

   en.wikipedia.org/wiki/Earth's_magnetic_field

   Earth's magnetic field, predominantly dipolar at its surface, is distorted further out by the solar wind. This is a stream of charged particles leaving the Sun's corona and accelerating to a speed of 200 to 1000 kilometres per second. They carry with them a magnetic field, the interplanetary magnetic field (IMF).

4. Magnetic levitation - Wikipedia

   en.wikipedia.org/wiki/Magnetic_levitation

   Magnetic levitation can be stabilised using different techniques; here rotation (spin) is used. 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 force and any other forces.

5. Edison Academy Magnet School - Wikipedia

   en.wikipedia.org/wiki/Edison_Academy_Magnet_School

   www .mcmsnj .net /edison. The Edison Academy Magnet School (formerly known as the Middlesex County Academy for Science, Mathematics and Engineering Technologies) is a four-year career academy and college preparatory magnet public high school located on the campus of the Middlesex County College in Edison, in Middlesex County, New Jersey.

6. Force between magnets - Wikipedia

   en.wikipedia.org/wiki/Force_between_magnets

   Force between magnets. Magnets exert forces and torques on each other through the interaction of their magnetic fields. The forces of attraction and repulsion are a result of these interactions. The magnetic field of each magnet is due to microscopic currents of electrically charged electrons orbiting nuclei and the intrinsic magnetism of ...

7. Electromagnet - Wikipedia

   en.wikipedia.org/wiki/Electromagnet

   An electromagnet is a type of magnet in which the magnetic field is produced by an electric current. Electromagnets usually consist of wire wound into a coil. A current through the wire creates a magnetic field which is concentrated in the hole in the center of the coil.
