Definition of electromagnet in English:


Translate electromagnet into Spanish


  • A soft metal core made into a magnet by the passage of electric current through a coil surrounding it.

    ‘During braking, the metal wheels are exposed to a magnetic field from an electromagnet, generating eddy currents in the wheels.’
    • ‘Magnets, either conventional electromagnets or superconducting magnets, are placed along the accelerator tube at regular intervals.’
    • ‘The mass acted upon by the coil elements can be a permanent magnet or magnets, or electromagnets.’
    • ‘In order to generate a magnetic field that can be said to propagate, it is necessary to produce a changing field by turning on an electromagnet or removing a magnet from a magnetic shield such as a superconducting box.’
    • ‘As these charged particles swirl, they generate magnetic fields just the way electrons moving in an electromagnet's coiled wire do.’
    • ‘A power supply for applying a voltage to a scanning electromagnet for deflecting a charged particle beam has a first power supply unit having no filter and a second power supply unit having a filter.’
    • ‘This, for instance, is how we ordinarily think of the magnetic field of an electromagnet, which is sustained only so long as an electric current passes through the magnet's coils.’
    • ‘Modern circular accelerators place klystrons and electromagnets around a circular copper tube to speed up particles.’
    • ‘By experimenting with magnets and electromagnets it was learnt how a motor is turned by electricity.’
    • ‘If you are having trouble finding a magnet around the house, two possible sources include a can opener and an electromagnet that you make yourself.’
    • ‘In the simplest case, the wires carrying the electrical signals are used to form an electromagnet which attracts and releases a metal diaphragm.’
    • ‘Plus, he says, their carbon cores could make them stronger than steel, so an electromagnet made from the wires wouldn't need a heavy structure to support it.’
    • ‘It is this small magnetic field that is the basis of an electromagnet.’
    • ‘Finally, after calibration of the apparatus, the force acting on the particle can be determined by measuring the currents driving the electromagnets.’
    • ‘It is also used for magnetic poles of electromagnets.’
    • ‘They mounted two flat, semicircular metal chambers between the faces of a powerful electromagnet.’
    • ‘What difference does voltage make in the strength of an electromagnet?’
    • ‘When cooled to extremely low temperatures, electromagnets demonstrate an unusual behavior: For the first few nanoseconds after electricity is applied to them, they vibrate.’
    • ‘Other rhenium alloys are used in making temperature control devices, such as thermostats; vacuum tubes, like those in a television set; and electromagnets, electrical contacts, and thermocouples.’
    • ‘As early as 1826 the inventor of the electromagnet William Sturgeon had tried to open pallets with his invention.’
