Electromagnet in a sentence

The central spike forms one pole of an electromagnet and is surrounded by an annular space, and around that is the other pole of the electromagnet, with a radial magnetic field in between.

Stark was nearly killed by the attack on the U.S. Army convoy but his life by a man named Yinsen (Shaun Toub), who built a crude electromagnet to keep shrapnel from piercing Tony's heart.

A device so formed around an iron core may act as an electromagnet, generating a strong, well-controlled magnetic field.

An electromagnet is made from a coil of wire that acts as a magnet when an electric current passes through it but stops being a magnet when the current stops.

An infinitely long cylindrical electromagnet has a uniform magnetic field inside, and no magnetic field outside.

A pickling plant was established on-site to clean the pipes and fittings.sfn Giant electromagnet Alpha I racetrack for uranium enrichment at Y-12 plant, Oak Ridge, Tennessee, circa 1944–45.

Electrodynamic An electrodynamic movement uses an electromagnet instead of the permanent magnet of the d'Arsonval movement.

However, unlike a permanent magnet that needs no power, an electromagnet requires a continuous supply of current to maintain the magnetic field.

However, very small variations in the calibration of the electric current in the electromagnet introduce minuscule frequency variations among different caesium oscillators.

In the late nineties, a team at Columbia University and MIT developed the Levitated dipole a fusion device which consisted of a superconducting electromagnet, floating in a saucer shaped vacuum chamber.

Many relays use an electromagnet to operate a switching mechanism mechanically, but other operating principles are also used.

Much later, in 1955, G.B. Yntema citation succeeded in constructing a small 0.7-tesla iron-core electromagnet with superconducting niobium wire windings.

Newer versions use an electronic track with a carriage or an electromagnet to pull the ball between holes.

Over this was placed a circular disk of paper; an electromagnet with the embossing point connected to an arm traveled over the disk; and any signals given through the magnets were embossed on the disk of paper.

Properly the term 'Calutron' applies to a multistage device arranged in a large oval around a powerful electromagnet.

Realizable caesium frequency standards use a strong electromagnet to deliberately introduce a magnetic field which overwhelms that of the Earth.

Soon after discovering superconductivity in 1911, Kamerlingh Onnes attempted to make an electromagnet with superconducting windings but found that relatively low magnetic fields destroyed superconductivity in the materials he investigated.

The dees are located between the poles of a large electromagnet which applies a static magnetic field B perpendicular to the electrode plane.

The electric clock's mainspring is wound either with an electric motor or with an electromagnet and armature.

The electromagnet loses them when current and magnetic field are removed.
