Is earths magnatic field also know as an auroa?
Nope, but they are related. At the north and south poles, magnetism is weakest. As a result, high-energy particles from the Sun are allowed through. These particles collide with the uppera tmosphere, knocking photons loose. Photons are the 'light' that we see. Different energy levels produce different colors in the resulting Aurora.
What is magnatic tape?
magnatic tape is a medium for magnatic recording.this is usedfor video rcording,audio recording or for computer data storage. It was originally developed in Germany.Gramaphone is a example for which used in the past as a magnatic storeage.Gramaphone disk is made from P.V.C.(polivinail cholide)it is an analouge sound
Is earths magnetic field the weakest at its poles?
No, but at the poles the field (because of the orientation of the field lines) offers the least protection.
Where is the Earths magnetic field at its strongest?
The Earth's magnetic field is strongest at the North and South magnetic poles, which are not the same as the geographic North and South poles. The magnetic field strength varies at different locations on the Earth's surface.
What is the property of a body that causes it to have weight in a gravitational field?
The mass of a body is the property that causes it to have weight in a gravitational field. Weight is the gravitational force exerted on an object, and it is directly proportional to the mass of the object.
Does earth have a magnatic field?
Yes
Which planet does not have a magnatic field?
Pluto. Too Cold
Where does the convection that causes earths magnetic field?
The convection that causes Earth's magnetic field happens in Earth's molten outer core.
Can gravity exist without a magnatic field?
It can, and it does. There's no connection between the two.
Is any magnatic field proof material?
Yes, a magnetic field won't penetrate a superconductor. That's called the Meissner effect.
What is the principle of operation of three phase squirrel cage induction motar?
three phase induction motor is like a rotating transformer, works on the principle of faraday's law of electromagnetic induction. when ever three phase supply is given rotating magnetic field is produced (rotating magnetic field is produced because current flowing through each phase is delayed 6.66mSec) and the stationary conductor (rotor) is cut by the rotating magnatic field so emf is induced in the conductor (rotor) since rotor is short circuited current flows and this current produces magnatic field. magnatic field produced by the rotor interacts with the rotating magnatic field. this interaction of fields produces movement in the conductor(rotor)(since it is allowed to rotate).
How electrostatic force balance electron to revolve around nucleus?
because electons make an magnatic field makes the attraction of each electorn to other whether they are of same charge but because of magnatic field they perfom as opposite and attract each other thats why they easly revolve in nucleus
What causes changes to earths land form?
what causes changes to earths landform
How are the Earths magnetic field made?
It is made by the movement of the earths core and magma field
Why photon show both electric and magnatic field?
Protons are positively charged that's why they show electric field while magnetic field develops when electric field is in either direction so protons develops magnetic fields also.
Is earths core a source of earths magnetic field?
Yes.
What causes all of the changes that take place in earths atmosphere?
what causes all of the changes that take place in earths atmosphere is the tilt of the earths axis
