Imaging technique that detects the energy emitted by hydrogen atoms in a magnetic field?
Magnetic Resonance Imaging (MRI) is the imaging technique that detects the energy emitted by hydrogen atoms in a magnetic field. When exposed to the magnetic field, hydrogen atoms align their spin, and then radiofrequency pulses cause them to emit energy that is detected by the MRI machine to create detailed images of the body's internal structures.
What is the relation between the earth's magnetic field and the northern light?
The Earth's magnetic field plays a crucial role in the formation of the northern lights. When charged particles from the sun are directed towards Earth, they interact with the magnetic field and are funneled towards the poles. As these particles collide with gases in the atmosphere, they emit light, creating the beautiful auroras in the northern and southern regions.
How do the arora borialis work?
Charged particles emitted from the sun get caught in the "magnetic wells" at the earth magnetic poles caused the the shape of the earth's magnetic field, exciting the air molecules there, and causing them to emit light.
How does MRI produce an image of the internal structures of the body?
MRI, or magnetic resonance imaging, uses a strong magnetic field and radio waves to create detailed images of the internal structures of the body. The magnetic field aligns the hydrogen atoms in our body, and when radio waves are applied, these atoms emit signals that are used to create the images.
Electrons are emitted from a conductor when the conductor is?
>bombarded by high-speed electronsThat's like saying "water comes out of a pipe when water is poured into the pipe" Conductors don't EMIT electrons (any more than any material), but they allow electrons to flow freely within themselves. That is called a current.On that note, a current flows through a conductor when it is moved through a magnetic field. This is how generators work.Any material can be made to emit electrons by adding electrons to it. That's like saying a full cup will emit water if more water is added to it.ACTUALLY they are emitted. look it up.
Do the solar flares emit CMEs?
Yes, solar flares can emit coronal mass ejections (CMEs) as they release a burst of energy and magnetic field into space. CMEs are massive eruptions of magnetized plasma from the Sun's corona that can affect space weather and produce geomagnetic storms when they interact with the Earth's magnetic field.
Do all current carrying conductors emit electromagnetic waves?
No. Only those carrying AC. Those carrying DC have a constant magnetic field around them and emit no waves.
Where do the northern lights form?
Particles from the sun (by solar wind) hit a magnetic field of the Earth and emit radiation.in the north, and the southern in the south.

What causes hydrogen atoms to line up during an MRI?
In an MRI, hydrogen atoms in the body align due to the strong magnetic field generated by the MRI machine. This magnetic field causes the protons in hydrogen atoms, which are abundant in water and fat tissues, to align with the magnetic field direction. When a radiofrequency pulse is applied, these protons are temporarily knocked out of alignment. As they return to their original alignment, they emit signals that are detected and used to create images of the body's internal structures.

How much radiation does MRI emit?
MRI does not emit ionizing radiation like X-rays or CT scans. Instead, it uses a magnetic field and radio waves to create detailed images of the body's internal structures without exposing the patient to harmful radiation.
How nuclear magnetic resonance takes place?
Nuclear magnetic resonance means nucleii in a magnetic field absorb and re-emit electromagnetic radiation. This absorption and emission causes a resonance. The parts of a nucleus each have an intrinsic quantum property called spin, which is magnetic moment. The total spin of the nucleus is determined by the sum of the parts. When subjected to the oscillating magnetic field, the nucleus shifts states depending on the orientation and number of the protons and neutrons in it.
What causes the lights?
The Sun's magnetic field produces charged particles and these charged particles are usually radiated out into space. Sometimes these charged particles may be caught in Earth's magnetic field and as they enter the upper atmosphere of Earth, they are in contact with other gases in the upper atmosphere and emit light and colors. The solar wind reacts to the Earth's magnetic field and then spreads across the ionosphere (the upper, charged layer of our atmosphere).
The shape of the magnetic fields around the earth is influenced by the 'aurora borealis' or 'solar wind'?
The shape of Earth's magnetic field is influenced by the interaction between the solar wind and the magnetosphere. The aurora borealis is a result of charged particles from the solar wind interacting with Earth's magnetic field and atmosphere near the poles, causing them to emit light. The solar wind, which is a stream of charged particles released from the sun, can distort the shape of Earth's magnetic field as it interacts with it.
