What creates the magnetic field? A magnetic field can be created with moving charges, such as a current-carrying wire. A magnetic field can also be created by the spin magnetic dipole moment, and by the orbital magnetic dipole moment of an electron within an atom. ...
Since the Industrial Revolution, humans have generated 1.5 trillion tons of CO2pollution, and the total amount of stored ocean carbon is put at an astounding 50 times greater than in the atmosphere. Moreover, the CO2exchange between those realms is a delicate balance. If the ocean stores too ...
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...
Does the magnetic force obey Newton's third law? What creates a magnetic field? What does the magnetism in an MRI help accomplish? What does the magnetic field around a solenoid look like? Is magnetism the strong nuclear force? What affects the strength of a magnetic field?
What is magnetic field simulation? What creates a magnetic field? What are the properties of a magnetic field? What is a changing magnetic field? What can produce magnetic fields? What does the magnetic field around a solenoid look like?
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...
The magnetic field was defined so that pictures like this made sense. Classical physics: A when a charge moves in some direction it creates a magnetic field that wraps around it. The direction of the field can be found using (one of) the “right hand rule(s)”. ...
tangled (缠绕的) wires and no more having to sit and hold your cell phone near a power socket in the corner of the room.WiTricity,a US company,has invented technology that can power objects up to 2.4meters away.It uses a special plug-in coil (线圈) that creates a magnetic field.60...
a conductor when the current change in the conductor is at the rate of 1 ampere per second. an electric current flowing through a conductor creates a magnetic field around it. the strength of the field depends upon the magnitude of the current. the generated magnetic field follows any changes...
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 ...
