No one really knows because it all doesn't flip at the same time. Some areas will start to flip and mix with the magnetic field, thus causing it to flip. This is scheduled to happen in the next millennium=1000 years.

What is released when protons flip in a magnetic field?
Energy is released when protons flip in a magnetic field. :)))))
When did the earths magnetic field flip?
About 780 000 years ago was when the earth's magnetic field last flipped. In summer 1960-61, a USARP party led by Franz van der Hoeven, left Scott Base, Antarctica to traverse Victoria Land, the territory lying to the west of the Ross Sea. In the course of this traverse they found a series of gravity anomalies which inferred a strike of a group of bolides. This has more recently been confirmed by satellite measurement. The date of this impact is coincident with the last geomagnetic reversal, but no cause-and-effect is yet shown. This area is close to the location of the South Magnetic Pole. The magnetic field is believed to be caused by electrical currents in the magma, running approximately parallel to the equator. [Or the net sum of a parallel of such currents.] Slight disturbances in these conductivity paths could easily move the route of the current, thus changing the position of the poles.
What law states that the induced current is always in such a direction as to oppose the change in the magnetic field that generated it?
It is called Lenz's law. Refer to the below related link for its Wikipedia article. It is a direct result of Faraday's law. If you look at the equation.. ε = - dΦ/dt it is basically the negative sign that says the magnetic field of the induced current will be in the oppose direction of the change in the magnetic field. Do the following things. • Curl the fingers of your right hand. • Let your thumb represent the direction that the magnetic flux is increasing. • Because of the negative sign, the electric field, and thus the generated current will be in the opposite direction of you fingers. • So flip your hand over so that your fingers point in the opposite direction. • Now your thumb points in the opposite direction and that represents the direction of the magnetic field that the current generates.
What happens when the magnetic poles flip?
the north pole becomes the southe pole and your compuses will as change
WHAT IS NMR frequency?
Electro magnetic radiation in the range of 60Mhz to 1000Mhz frequency necessary to cause a nucleus to spin flip ie the resonance frequency.

Is Earths magnetic field widening?
I am not sure what you mean by widening. The Earth's magnetic field is a result of the fact that the Earth has a molten Iron core and the planet is rotating quite rapidly. The strength of the magnetic field in these circumstances is dependent on the speed of rotation. As the Earths rotational speed is slowing (due to the friction of the tides caused by the moon) the Earth's magnetic field is gradually weakening over geological time scales but this is not significant in terms of human time. The other affect of the rotating Iron core on the magnetic field is what is called field inversions. In the same was as the Sun goes through an 11 cycle of activity during which the N and S magnetic poles flip, the Earth's poles also flip about once every 75-100 thousand years. There is some evidence that the Earth's poles are in the process of flipping at the moment and during this process, in the same was that the Sun develops Sun spots, multiple poles appear at various locations round the Earth. This effect could be said to distort (or widen) the Earths magnetic field.
How long does earths magnetic flip take?
An electromagnetic wave is a form of radiation consisting of waves of energy associated with electric and magnetic fields resulting from the acceleration of an electric charge. An electromagnetic wave travels like any other form of radiation or light, except for the fact that an electromagnetic wave moves perpendicular to an electric field and a magnetic field.
Is the magnetic pole near the Earths true North Pole a magnetic south pole or a magnetic north pole?
Earths geographic North Pole is also currently a magnetic north pole. This is however not always the case because over geological time scales the Earth's magnetic poles flip as a result of changes of flow in Earth's molten core which produces Earth's magnetic field.
Earths magnetic poles reverse approximately every years?
The process of the reversal of the Earth's magnetic poles is called a magnetic flip. This occurs every 4 or 5 times per million years.
Does Earth's magnetic field change?
Yes constantly, it is affected by the Solar wind and about every 100 thousand years the poles flip.
What change do you think there would be in the magnetic fied if the current went down instead of up the wire?
I think the direction of the magnetic field at every point would flip to the exact opposite direction. I could be wrong.
Are flip flops magnets?
It's possible there may be some company producing a magnetic product they call "flip flops" and/or flip flop sandals that are magnetic, either miniature or full, wearable sized; but, no, flip flops are not magnets, generally speaking. Flip flops are a simple type of sandal.
What Is The Difference Between Magnetic reversal reversed field and normal field?
A magnetic reversal happens in a magnetic field generated naturally in a spinning object such as the Earth or the Sun. In cases where the magnetic field is generated as a result of spin the polarity of the field (where the north and south poles are) flips on a regular periodic basis. For instance about once every 11 years on the Sun and about every 100 thousand years on the Earth. This flipping of the field is called a 'magnetic reversal' on Earth and a solar cycle on the Sun. Between flipping events the magnetic field of the body is regular or normal (but of cause in the opposite orientation each flip) but during the flipping process the field is chaotic with many minor polar regions appearing round the body (as sunspots during a solar maxima) and presumable a similar but slower thing happens on Earth (we do not know yet but it looks as though the Earth's poles may be beginning to reverse at the moment).
How can magnetism be induced?
You can turn a magnetic field produced by a current on or off by simply turning the current on of off, You can change the direction of the magnetic field by reversing the direction of the current, You can also change the strength of a magnetic field produced by a current by looping the wire, by winding a wire with a current into many loops you strengthen the magnetic field in the center of the coil.
