  2. Eddy current - Wikipedia

    en.wikipedia.org/wiki/Eddy_current

    The Lorentz force of the magnetic field on the electrons in the metal induces a sideways current under the magnet. The magnetic field, acting on the sideways moving electrons, creates a Lorentz force opposite to the velocity of the sheet, which acts as a drag force on the sheet. The blue arrows are counter magnetic fields generated by the ...

  3. Epstein frame - Wikipedia

    en.wikipedia.org/wiki/Epstein_frame

    Epstein frame. An Epstein frame or Epstein square is a standardised measurement device for measuring the magnetic properties of soft magnetic materials, especially used for testing of electrical steels. The International Standard for the measurement configuration and conditions are defined by the standard IEC 60404-2:2008 Magnetic materials ...

  4. Permeability (electromagnetism) - Wikipedia

    en.wikipedia.org/wiki/Permeability...

    Scientists. v. t. e. In electromagnetism, permeability is the measure of magnetization produced in a material in response to an applied magnetic field. Permeability is typically represented by the (italicized) Greek letter μ. It is the ratio of the magnetic induction to the magnetizing field as a function of the field in a material.

  5. Staple (fastener) - Wikipedia

    en.wikipedia.org/wiki/Staple_(fastener)

    A staple (from which the paper fastener was developed) A staple is a type of two-pronged fastener, usually metal, used for joining, gathering, or binding materials together. Large staples might be used with a hammer or staple gun for masonry, roofing, corrugated boxes and other heavy-duty uses. Smaller staples are used with a stapler to attach ...

  6. Stapler - Wikipedia

    en.wikipedia.org/wiki/Stapler

    A spring-loaded stapler. A stapler is a mechanical device that joins pages of paper or similar material by driving a thin metal staple through the sheets and folding the ends. Staplers are widely used in government, business, offices, workplaces, homes, and schools. [1]

  7. Induction cooking - Wikipedia

    en.wikipedia.org/wiki/Induction_cooking

    Induction cooking surfaces work well with any pans with a high ferrous metal content at the base. Cast iron pans and any black metal or iron pans are compatible. Stainless steel pans are compatible if the base of the pan is a magnetic grade of stainless steel. If a magnet sticks well to the bottom of the pan, it is compatible.

  8. Magnet keeper - Wikipedia

    en.wikipedia.org/wiki/Magnet_keeper

    A "horseshoe magnet" made of Alnico 5, about 1 inch high.The metal bar (bottom) is a keeper. A magnet keeper, also known historically as an armature, is a bar made from magnetically soft iron or steel, which is placed across the poles of a permanent magnet to help preserve the strength of the magnet by completing the magnetic circuit; it is important for magnets that have low magnetic ...
