In unmagnetized materials, magnetic domains face in different directions, canceling each other out. Whereas in magnetized materials, most of these domains are aligned, pointing in the same direction, which creates a magnetic field. The more domains that align together the stronger the magnetic force...
3. What creates the Earth's magnetic field (and why does it move)? 3.是什么创造了地球的磁场(为什么它会移动)? 4. Will we be able to predict catastrophic weather events (tsunami, hurricanes, earthquakes) more accurately? 4.我们是否能够更准确地预测灾害性事件(海啸、飓风、地震)? 5. What hap...
What creates a magnetic field? What is the fundamental source of electromagnetic radiation? What are the components of electromagnetic radiation? What are the properties of a magnetic field? What is scattering in quantum electrodynamics? What can absorb electromagnetic radiation?
This difference in potential generates a current flow both inside and outside the neuron, which creates a magnetic field. One such event, however, is still insufficient in generating a magnetic field large enough to be detected even by the mightiest of SQUIDs, so it is thought that the ...
When you run electricity into this electromagnet, it creates a magnetic field in the armature that attracts and repels the magnets in the stator. So the armature spins through 180 degrees. To keep it spinning, you have to change the poles of the electromagnet. The brushes handle this change ...
A phone with wireless charging placed on amagnetic wireless chargerfirst gets aligned with the magnets and then charged inductively. The most powerful wireless charger produces an alternating magnetic field which creates an electric current in a coil. The device then charges the batteries. With the...
a relay, a magnetic field needs to be created that is capable of closing the reed switch contacts. Reed switches can be used with permanent magnets (for example, to detect doors closing), but for the reed relays, th...
When the ignition switch is turned on, a low-voltage current flows through the primary winding of the ignition coil. The ignition coil transforms the low voltage from the battery into a high voltage output through electromagnetic induction. The primary winding creates a magnetic field when the ...
This creates a toroidal, or doughnut-shaped field, as the direction of the field propagates outward from the north pole and enters through the south pole. Earth itself is a giant magnet. The planet gets its magnetic field from circulating electric current within the molten metallic core, ...
