2. Magnet - Wikipedia

   en.wikipedia.org/wiki/Magnet

   A magnet's magnetic moment (also called magnetic dipole moment and usually denoted μ) is a vector that characterizes the magnet's overall magnetic properties. For a bar magnet, the direction of the magnetic moment points from the magnet's south pole to its north pole, [ 15 ] and the magnitude relates to how strong and how far apart these poles ...

3. Magnet school - Wikipedia

   en.wikipedia.org/wiki/Magnet_school

   Thomas Jefferson High School for Science and Technology in Fairfax, Virginia, one of the highest rated magnet schools in the United States. In the U.S. education system, magnet schools are public schools with specialized courses or curricula. Normally, a student will attend an elementary school, and this also determines the middle school and ...

4. Electromagnet - Wikipedia

   en.wikipedia.org/wiki/Electromagnet

   To concentrate the magnetic field in an electromagnet, the wire is wound into a coil with many turns of wire lying side by side. [2] The magnetic field of all the turns of wire passes through the center of the coil, creating a strong magnetic field there. [2] A coil forming the shape of a straight tube (a helix) is called a solenoid. [1] [2]

5. Electromagnetism - Wikipedia

   en.wikipedia.org/wiki/Electromagnetism

   A current is induced in a loop of wire when it is moved toward or away from a magnetic field, or a magnet is moved towards or away from it; the direction of current depends on that of the movement. [9] In April 1820, Hans Christian Ørsted observed that an electrical current in a wire caused a nearby compass needle to move. At the time of ...

6. Force between magnets - Wikipedia

   en.wikipedia.org/wiki/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 fundamental particles (such as electrons) that make up the mater
