2. Shading coil - Wikipedia

   en.wikipedia.org/wiki/Shading_coil

   This induced current creates an auxiliary magnetic flux which is 90 degrees out of phase from the magnetic flux created by the primary coil. [ 1 ] Frager spire or shading coil's purpose is to provide sizeable phase-shifted magnetic field (in blue) to keep the contactor on when the main coil flux (in red) passes through zero, avoiding unwanted ...

3. Electromagnetic forming - Wikipedia

   en.wikipedia.org/wiki/Electromagnetic_forming

   A pinched aluminium can, produced from a pulsed magnetic field created by rapidly discharging 2 kilojoules from a high-voltage capacitor bank into a 3-turn coil of heavy gauge wire. Electromagnetic forming ( EM forming or magneforming ) is a type of high-velocity, cold forming process for electrically conductive metals, most commonly copper and ...

4. Rotating magnetic field - Wikipedia

   en.wikipedia.org/wiki/Rotating_magnetic_field

   The rotating magnetic field is the key principle in the operation of induction machines.The induction motor consists of a stator and rotor.In the stator a group of fixed windings are so arranged that a two phase current, for example, produces a magnetic field which rotates at an angular velocity determined by the frequency of the alternating current.

5. Induction sealing - Wikipedia

   en.wikipedia.org/wiki/Induction_sealing

   As the container passes under the induction coil (sealing head), the conductive aluminum foil liner begins to heat as a result of the eddy currents being induced. The heat melts the wax, which is absorbed into the pulp backing and releases the foil from the cap. The polymer film also heats and flows onto the lip of the container.

6. Magnetic core - Wikipedia

   en.wikipedia.org/wiki/Magnetic_core

   A magnetic core is a piece of magnetic material with a high magnetic permeability used to confine and guide magnetic fields in electrical, electromechanical and magnetic devices such as electromagnets, transformers, electric motors, generators, inductors, loudspeakers, magnetic recording heads, and magnetic assemblies.

7. Heat press - Wikipedia

   en.wikipedia.org/wiki/Heat_press

   A heat press is a machine engineered to imprint a design or graphic on a substrate, such as a t-shirt, with the application of heat and pressure for a preset period of time. While heat presses are often used to apply designs to fabrics , specially designed presses can also be used to imprint designs on mugs, plates, jigsaw puzzles, caps, and ...
