Sentences with phrase «changing magnetic field»

He observed that changing magnetic fields creates electric currents, and moving electric charges generates magnetic fields.

The sun also generates massive magnetic fields and changes in solar activity changes these magnetic fields.

The alternating current creates a constantly changing magnetic field and, through some clever engineering, magnetizes the core of the motor as well.

Helmholtz coils change the magnetic field of whatever is between them.

Rose, who recently left UW for the University of Notre Dame in South Bend, Indiana, and his colleagues then turned to transcranial magnetic stimulation (TMS), a noninvasive method that uses rapidly changing magnetic fields to deliver a pulse of electrical current to the brain.

This was achieved using variable - gap undulators, that act as a radiator and whose resonant wavelength can be largely varied by changing the magnetic field strength.

But mole rats that built nests within changing magnetic fields showed strong activity in a brain region called the superior colliculus, which collects spatial cues and directs orienting behavior.

In the installation Interface I, German artist Ralf Baecker sculpts emergent behaviors by juxtaposing systems transversal to one another inspired by the earth's changing magnetic field while the Chinese artist aaajiao conjures up computer - generated landscapes and objects.

This inconstant behavior can be traced to changing magnetic fields in the solar atmosphere.

At any rate if you change the magnetic field around someone's temporal lobe it produces religious experiences, so when someone is having an experience, what is causing it?

In addition, because part of the inertia of a particle is due to the electromagnetic field around it, as you speed up such a particle the electric field produces a magnetic field, the changing magnetic field produces a back EMF, and this whole reaction of the field produces a resistance to acceleration.

The ripples spreading out below the pulsar like waves on a lake show where streams of electrons and positrons, shooting away from the pulsar at nearly the speed of light, begin to bunch up along the pulsar's changing magnetic field.

The changing magnetic field ensures that the rotor will never come to rest, and its strength — thousands of times more powerful than a typical refrigerator magnet — provides the necessary push to keep the train moving.

It supports a strong, changing magnetic field that varies year - to - year and reverses direction about every 11 years.

This changing current in the motor's windings produces causes a magnetic field to build and the changing magnetic field is what generates the back EMF which resists the current rushing through the motor.
