Helmholtz
coils change the magnetic field of whatever is between them.
Not exact matches
A copper
coil surrounding the sample detected
changes to the superconductor's
magnetic properties and allowed the team to sensitively measure tiny variations in how deep the
magnetic field reached inside the superconductor.
The team put monarchs in a flight simulator surrounded by a
magnetic coil, measuring responses to horizontal, vertical, and intensity
changes in the
magnetic field.
Inside the
coil is a rod of terbium dysprosium, which is a magneto - strictive material — its length
changes with the
magnetic field.
When a voltage is applied to a
coil, a
magnetic field is generated in which the alignment of the particles
changes so that they are perpendicular to the oil flow, thereby inhibiting its flow through the shock absorber channels.
