Definition of electromagnet in English: electromagnetnoun ɪˌlɛktrə(ʊ)ˈmaɡnɪtəˈlɛktroʊˌmæɡnət Physics A soft metal core made into a magnet by the passage of electric current through a coil surrounding it. 〔物理〕电磁体，电磁铁 Example sentencesExamples - 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 early as 1826 the inventor of the electromagnet William Sturgeon had tried to open pallets with his invention.
- 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.
- They mounted two flat, semicircular metal chambers between the faces of a powerful electromagnet.
- 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.
- It is also used for magnetic poles of electromagnets.
- What difference does voltage make in the strength of an electromagnet?
- By experimenting with magnets and electromagnets it was learnt how a motor is turned by electricity.
- The mass acted upon by the coil elements can be a permanent magnet or magnets, or electromagnets.
- 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.
- During braking, the metal wheels are exposed to a magnetic field from an electromagnet, generating eddy currents in the wheels.
- Modern circular accelerators place klystrons and electromagnets around a circular copper tube to speed up particles.
- 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.
- Magnets, either conventional electromagnets or superconducting magnets, are placed along the accelerator tube at regular intervals.
- In the simplest case, the wires carrying the electrical signals are used to form an electromagnet which attracts and releases a metal diaphragm.
- 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.
- It is this small magnetic field that is the basis 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.
- As these charged particles swirl, they generate magnetic fields just the way electrons moving in an electromagnet's coiled wire do.
- Finally, after calibration of the apparatus, the force acting on the particle can be determined by measuring the currents driving the electromagnets.
