Electromagnetic Coil Strength from Moving Liquids?

In summary, the conversation discusses the concept of using a charged fluid, such as the oil used in an oil-based van de graff generator, to create a stronger magnetic field than is possible with a copper coil. It is suggested that a charge density of 6L/min in 3/8" ID tubing could produce a field 60362.17 times more powerful than a copper wire. However, the question is raised about the charge density that can be achieved with the ionic fluid, as electron density is not dependent on macroscopic ionized molecules. The speaker also asks where this information can be found and if it is related to the voltage at which the fluid is charged.

I was reading about drift velocity and according to http://amasci.com/miscon/speed.html 100VDC at 1A moving through ~12 AWG wire would produce an electron velocity of 8.4 cm/hr. Since that is incredibly slow I'm curious if a charged fluid (something like the oil used in an oil-based van de graff generator with an external high-voltage charge applied to it to) could be used to generate a much more powerful magnetic field than is possible with a copper coil? Something on the order of 507042.25 cm/hr (6L/min in 3/8" ID tubing) could easy be attained with the same wattage of off the shelf components suggesting if the mobile ions are the same the coil would produce a field ~60362.17 times more powerful than a copper wire. Am I missing something here or is this feasible?

What charge density can you accomplish with your ionic fluid? Electron density is not dependent on macroscopic ionized molecules.

1. What is an electromagnetic coil?

An electromagnetic coil is a type of conductor that consists of a series of loops or turns of wire. When an electric current flows through the coil, it creates a magnetic field.

2. How does the movement of liquids affect the strength of an electromagnetic coil?

The movement of liquids can affect the strength of an electromagnetic coil in two ways. First, if the liquid is conductive, it can induce an electric current in the coil, which can strengthen or weaken the magnetic field. Second, the movement of the liquid can also create turbulence, which can disrupt the magnetic field and weaken its strength.

3. What factors determine the strength of an electromagnetic coil from moving liquids?

The strength of an electromagnetic coil from moving liquids depends on several factors, including the velocity and direction of the liquid, the conductivity of the liquid, and the design of the coil itself.

4. How can the strength of an electromagnetic coil from moving liquids be measured?

The strength of an electromagnetic coil from moving liquids can be measured using instruments such as a Gaussmeter or Magnetometer, which can detect and measure the strength of a magnetic field.

5. What are some real-world applications of studying electromagnetic coil strength from moving liquids?

Studying the strength of electromagnetic coils from moving liquids has various real-world applications, such as in hydropower generation, where the movement of water can be used to generate electricity. It is also essential in industries that use electromagnetic coils for various purposes, such as in MRI machines and electric motors. Additionally, this research can also help in understanding and predicting the behavior of Earth's magnetic field, which is affected by the movement of molten iron in the Earth's core.
