Electromagnetic effect on gases

In summary, the conversation discusses the effect of electromagnetic fields on gases, specifically H2 gas. It is mentioned that H2, a neutral and non-polar molecule, does not respond to electric fields unless they are high enough to ionize the molecule. It is also a weak diamagnetic material and is slightly repelled by magnetic fields. The conversation then brings up the use of superconducting electromagnets in MRI machines to align H2 molecules in the human body. The question is raised whether H2 gas can be moved in gaseous form under superconducting high magnetic fields, and if any other paramagnetic/diamagnetic gases can be moved. A video is referenced discussing paramagnetism and diamagnetism, and the possibility

Are there any research or paper regarding electromagnetic effect on gases. For example does H2 gas physically move under electromagnetic field?

H2, being both a neutral and non-polar molecule, doesn't respond to electric fields unless they are high enough to ionize the molecule. In addition, it is a weak diamagnetic material and is very, very slightly repelled by a magnetic field. For most practical purposes, no, H2 gas doesn't move under the influence of electromagnetic fields.

Thank you for your reply. MRI scanning machines use superconducting electromagnets to align the H2 molecules in a human body in water form. So with super conducting high magnetic ( as even mentioned by you in your earlier reply) is it possible to move the H2 in gaseous form. If No then are any other paramagnetic/diamagnetic gases able to move (attract/repel) under superconducting magnetic fields. Actually a video online has explained this, The link is " https://www.khanacademy.org/science...ions-jay-sal/v/paramagnetism-and-diamagnetism" seeing this video i was wondering if any gases move due to electromagnetic effect ( high field probably)?

In a field of 1 Tesla at what velocity will oxygen gas molecules be pulled? What is the force acting on O2 molecules. Do we have any formula to calculate this?
 

1. What is the electromagnetic effect on gases?

The electromagnetic effect on gases refers to the interaction between electromagnetic radiation and gas molecules. This interaction can cause changes in the behavior and properties of gases, such as ionization, excitation, and heating.

2. How does electromagnetic radiation affect gas molecules?

Electromagnetic radiation can affect gas molecules in several ways. It can cause them to absorb energy and become excited or ionized, resulting in changes in their chemical and physical properties. It can also induce molecular motion, leading to heating of the gas.

3. What is the role of electromagnetic fields in the behavior of gases?

Electromagnetic fields play a crucial role in the behavior of gases. They can interact with charged particles in the gas, causing them to move and creating currents. These currents can then produce magnetic fields, leading to further interactions and changes in the gas's behavior.

4. How does the composition of a gas affect its response to electromagnetic radiation?

The composition of a gas can significantly affect its response to electromagnetic radiation. Different gas molecules have different energy levels, and therefore, they will absorb and emit radiation at different wavelengths. This can result in unique spectral signatures for different gases, making them useful for identifying and studying atmospheric and interstellar environments.

5. Can electromagnetic radiation be used to control gases?

Yes, electromagnetic radiation can be used to control gases. By manipulating the properties of the radiation, such as its intensity and frequency, it is possible to influence the behavior of gas molecules. This can be used in various applications, such as plasma physics, gas lasers, and gas sensing technologies.
