Tough tough question: Calculating magnetic Flux in water

In summary, a cylindrical 1.61 tesla magnet with pole orientations (+)_)- is being spun at 350RPMs in a cylindrical body of water, which has dimensions of 19 inches tall and 13.5 inches in diameter. The magnet is centered in the water and has a propeller on top, creating a vortex with a diameter of 6 inches at the surface and 4 inches at the magnet. The objective is to determine the change in magnetic flux to calculate the amount of EMF produced, regardless of whether the water is moving or stationary. The relative magnetic permeability of water is 1, so it has no effect on the magnetic flux or field.

Hey all, so i have a cylindrical 1.61 tesla magnet with pole orientations (+)_)- being spun at 350RPMs in a cylindrical body of water. The body of water dimensions are 19inches tall, and 13.5 diameter. The magnet is centered in the container of water.
Also, the magnet is spinning with a propeller on the top of it so it is generating a vortex. the vortex is approximately 6inches in diameter at the surface of the water, and at the point it reaches the magnet it is about 4inches in diameter. I am really trying to determine the change in magnetic flux that way i can determine how much EMF is being produced. :redface: So, if anyone can help me it would be really appreciated.

It doesn't matter whether the water is moving or stationary. Water has relative magnetic permeability = 1 so it has no effect on magnetic flux or field.
 

1. How do you calculate magnetic flux in water?

In order to calculate magnetic flux in water, you will need to know the strength of the magnetic field and the area of the surface where the magnetic field passes through the water. The formula for magnetic flux is Φ = BAcosθ, where B is the magnetic field strength, A is the area of the surface, and θ is the angle between the magnetic field and the surface.

2. What units are used to measure magnetic flux?

Magnetic flux is typically measured in Weber (Wb) or Tesla-square meters (Tm²).

3. Can magnetic flux be measured directly in water?

No, magnetic flux cannot be measured directly in water. In order to measure it, you would need to use specialized equipment such as a Gaussmeter to measure the magnetic field strength and a surface area measurement tool to determine the area of the surface.

4. How does the presence of impurities in water affect magnetic flux?

The presence of impurities in water can affect the magnetic flux by altering the magnetic permeability of the water. This means that the water may be more or less responsive to the magnetic field, resulting in a change in the calculated magnetic flux.

5. Can magnetic flux in water be used for practical applications?

Yes, magnetic flux in water can be used for various practical applications such as water treatment, biomedical research, and energy generation. By manipulating the magnetic flux in water, scientists are able to control the movement of particles and ions, which can have numerous applications in different industries.
