What is released when protons flip in a magnetic field?
When protons flip in a magnetic field, they release radiofrequency energy. This phenomenon is the basis for magnetic resonance imaging (MRI), a technique used in medicine to create detailed images of the body's internal structures.
What forms when earths magnetic field changes direction?
When Earth's magnetic field changes direction, it results in a phenomenon known as geomagnetic reversal or magnetic flip. This process involves the magnetic north and south poles switching positions. These reversals have occurred throughout Earth's history and have been recorded in the rock record.
When protons flip charge in a magnetic field what is released?
When protons flip charge in a magnetic field, they release photons. This process is known as magnetic resonance and is the principle behind techniques such as magnetic resonance imaging (MRI) used in medical diagnosis.
Why do electro-magnets stop working when you flip the switch?
When you flip the switch to turn off the electromagnet, the flow of electric current stops, which in turn stops the magnetic field from being produced by the coil. The magnetic field is generated by the flow of electric current through the coil, so cutting off the current stops the magnetic field, causing the electromagnet to stop working.
What evidence suggests that earth's magnetic field may swap around in the futurw?
Evidence from magnetic minerals in ancient rocks suggests that Earth's magnetic field has reversed multiple times in the past. These reversals are recorded in the geological record as "flip-flops" of the magnetic field's orientation. Additionally, studies of the Earth's magnetic field strength and its decreasing intensity over time support the idea that a reversal may occur in the future.

How have Earths magnetic poles reversed many times during Earths history?
Earth's magnetic poles have reversed many times in the past due to changes in the Earth's molten outer core. As the molten metal moves, it generates the Earth's magnetic field. Over time, this movement can cause the magnetic field to weaken, flip, and establish a new polarity. The process of pole reversals is a natural part of the Earth's geophysical history.
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.
What change do you think there would be in the magnetic fied if the current went down instead of up the wire?
If the current direction in the wire changes from going up to going down, the direction of the magnetic field around the wire will reverse. This is governed by the right-hand rule, where the direction of the magnetic field is perpendicular to the direction of current flow. Overall, the magnitude of the magnetic field would remain the same, but its direction would be opposite.
Why do electro-magnets stop working when you flip the switch?
When you flip the switch to turn off the electromagnet, the flow of electric current stops, which in turn stops the magnetic field from being produced by the coil. The magnetic field is generated by the flow of electric current through the coil, so cutting off the current stops the magnetic field, causing the electromagnet to stop working.
How often does the sun's poles flip?
The sun's magnetic poles flip approximately every 11 years, coinciding with the sunspot cycle. This phenomenon is known as solar magnetic field reversal.
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.
