2. Figure skating lifts - Wikipedia

   en.wikipedia.org/wiki/Figure_skating_lifts

   Judges look for the following when evaluating twist lifts: the speed at entry and exit; whether or not the woman performs a split position while on her way to the top of the twist lift; her height once she gets there; clean rotations; a clean catch by the man (accomplished by placing both hands at the woman's waist and without any part of her ...

3. Arago's rotations - Wikipedia

   en.wikipedia.org/wiki/Arago's_rotations

   Fig. 4.—Faraday disc machine. Poisson, steeped in Coulomb's notions about magnetic action at a distance, essayed to build up a theory of magnetism of rotation, affirming that all bodies acquire a temporary magnetism in the presence of a magnet, but that in copper this temporary magnetism took a longer time to die away. In vain did Arago point ...

4. Flip-disc display - Wikipedia

   en.wikipedia.org/wiki/Flip-disc_display

   Flip-disc display elements (close up). The disc rotates on the shaft that is carried in the two triangular posts. The magnet that powers the rotation can be seen embedded in the disc. Under the disc is the driving solenoid; when powered, a field is induced into the two posts, flipping the discs. Rotation stops when the disc hits the post.

5. Magnetic particle clutch - Wikipedia

   en.wikipedia.org/wiki/Magnetic_particle_clutch

   A magnetic particle clutch is a special type of electromagnetic clutch which does not use friction plates. Instead, it uses a fine powder of magnetically susceptible material (typically stainless steel ) to mechanically link an otherwise free-wheeling disc attached to one shaft, to a rotor attached to the other shaft.

6. Torsion spring - Wikipedia

   en.wikipedia.org/wiki/Torsion_spring

   A coil of wire attached to the pointer twists in a magnetic field against the resistance of a torsion spring. Hooke's law ensures that the angle of the pointer is proportional to the current. A DMD or digital micromirror device chip is at the heart of many video projectors. It uses hundreds of thousands of tiny mirrors on tiny torsion springs ...

9. Electromagnetic clutches and brakes - Wikipedia

   en.wikipedia.org/wiki/Electromagnetic_clutches...

   The magnetic field that is generated in the wire, from the current, is known as the "right hand thumb rule". (V-1) The strength of the magnetic field can be changed by changing both wire size and the amount of wire (turns). EM couplings are similar; they use a copper wire coil (sometimes aluminum) to create a magnetic field.
