A hair clipper, often individually called the apparent plurale tantum hair clippers (in a similar way to scissors), is a specialised tool used to cut human hair. Hair clippers work on the same principle as scissors , but are distinct from scissors themselves and razors .
An electromagnet is a type of magnet in which the magnetic field is produced by an electric current. Electromagnets usually consist of wire (likely copper) wound into a coil. A current through the wire creates a magnetic field which is concentrated along the center of the coil. The magnetic field disappears when the current is turned off.
Magnetic separation is also useful in mining iron as it is attracted to a magnet. [3] Another application, not widely known but very important, is to use magnets in process industries to remove metal contaminants from product streams. [1] This takes a lot of importance in food or pharmaceutical industries.
In fact, a protein found in human hair called L-cysteine is sometimes used as an additive to certain foods. L-cysteine is an amino acid found in keratin, which some food manufacturers use to ...
Be careful with it at first to prevent any accidental injuries on your fingers—but once you get used to them, they’re sure to become your best hair cutting friend. Size : 9.02 x 3.98 x 1.14 in ...
People alleged to have such an ability are often called human magnets. Although metal objects are the most prevalent material of attraction, some "human magnets" are also able to stick other types of materials to their skin, such as glass , porcelain , wood or plastic as well as metals with no ferromagnetic properties, such as brass and ...
Electromagnetic or magnetic induction is the production of an electromotive force (emf) across an electrical conductor in a changing magnetic field. Michael Faraday is generally credited with the discovery of induction in 1831, and James Clerk Maxwell mathematically described it as Faraday's law of induction .
Magnetic field-assisted finishing, sometimes called magnetic abrasive finishing, is a surface finishing technique in which a magnetic field is used to force abrasive particles against the target surface. [1] As such, finishing of conventionally inaccessible surfaces (e.g., the inside surface of a long curved pipe) is possible.
