the directions, like on a compass, would be flipped as well as the magnetic fields. North would be the current south, and south would be the current north.
Has the magnetic field of the earth ever flipped? (i.e) North Pole would be South0?
In that case, the magnetic field would also reverse its direction.
No, our magnetic field has flipped several times over the years.CommentIf the questioner is referring to north and south magnetic poles, then, yes, a magnetic field is always allocated a direction from north to south (the direction a compass needle would point within that field).If, on the other hand, the questioner is referring to the locations called Magnetic North and Magnetic South... well, in modern times the magnetic polarity of Magnetic North is a south. But, in the past and, possibly in the future, the magnetic polarities have 'flipped' making the location, Magnetic North, a north pole -but the direction of the magnetic field is always north to south.
The idea is that the magnetic field of the device reacts with the external magnetic field. If the current is reversed, the magnetic field would also be reversed, and the reading would be the opposite.
you would get bummed by an alien
If we didn't have the earth's magnetic field, eventually all of the harmful and deadly rays from the sun would destroy life on earth.
Yes, but it would usually not have much practical use if the magnetic field flipped around all the time.
Then, at some point, the field would go into two directions simultaneously, which doesn't make much sense. The magnetic field lines form continuous closed loops.The tangent to the field line at a point represent the direction of the net magnetic field B,at that point.The magnetic field lines do not intersect,if they did, the direction of the magnetic field would not be unique at the point of intersection.
all the stuff on our fridge would fall off
Answer The answer is no, of course not! It is the magnetic polarity of the earth that is being flipped, not the locations of Magnetic North and Magnetic South. Remember, 'Magnetic North' and 'Magnetic South' are locations, not magnetic poles. So even if their magnetic polarities flip, the names of the locations won't ever change! All that would happen is that the magnetic field would reverse, and your compass would point to Magnetic South instead of Magnetic North.Think of it this way, if the magnetic polarity of the earth flips, you wouldn't swap the names 'Arctic' and 'Antarctic'! So, why would you swap the names 'Magnetic North' and 'Magnetic South'!!!!!
They are small areas in a material in which lots of atoms are oriented in the same direction, thus providing a magnetic field. The material's atoms would have to have a magnetic moment. If an external magnetic field is applied to such a material, the magnetic domains have a tendency to align to the magnetic field. And no, they are not "everywhere"; they only happen in certain magnetic materials such as iron.
Then the compass would react according to the magnetic field of the magnet.Then the compass would react according to the magnetic field of the magnet.Then the compass would react according to the magnetic field of the magnet.Then the compass would react according to the magnetic field of the magnet.
We expect Earth would still have a magnetic field during a reversal, but it would be weaker than normal with multiple magnetic poles. Radio communication would deteriorate, navigation by magnetic compass would be difficult and migratory animals might have problems. Many migratory animals use the geomagnetic field to orient themselves. However, even if Earth's magnetic field began a reversal, it would still take several thousand years to complete a reversal.
J. J. Thomson discovered the electron using an experiment involving cathode rays and a magnetic field. When subjected to the magnetic field, the cathode ray was deflected. If the magnetic field was flipped, the cathode ray was deflected in the opposite direction. This proved that a cathode ray was a stream of negatively charged particles that would later be deemed electrons.
If the magnetic field disappeared, we'll be in danger of gamma rays like solar winds and cosmic rays because magnetic fields shields those things. Without the magnetic field, compasses will no longer work and we would need to find other ways to measure direction to navigate. Also, birds depend on the magnetic field for navigation during migration and would no longer be able to do that.
It would still point magnetic north. Magnetic north and geographic north are different. If you had it precisely at magnetic north, it would have trouble pointing, but doing so would be almost impossible because the magnetic field is constantly fluctuating.
There are theories around that some birds can actually detect magnetic fields, which they use to navigate on long migrations.
If the current in the wire increases, the magnetic field also increases.
There would be a temporary weakening of the magnetic field during the reversal. After the reversal the only noticeable difference would be that compasses now point south instead of north. Navigation systems that use the magnetic field would need to be recalibrated.
The magnetic dynamo (molten iron core) that drives Earth's magnetic field would have to change direction or somehow flip around. This has happened many times in the past, and will happen again at some point.
The same direction as a compass needle would point when placed in the magnetic field.
you would induce voltage therefore chanfing the magnetic field
The magnetic field would become a magnetizing field as far as the magnetic material is concerned. If the material is dia magnetic then the electrons magnetic moment would get aligned in such a way as the resultant magnetic field within the material becomes perpendicular to the magnetizing one. In case of para, resultant would become parallel to the external In case of ferro, domains get aligned and so intense magnetic induction results.
To start if we didnt have a magnetic field we would be fried by the suns radiation. The northern lights are evidence that we have a magnetic field surrounding earth.
The magnetic field would reverse.
