Magnetic field from roting static charge

In summary, the conversation discusses the idea of creating a strong magnetic field using a rotating static electric charge. The individual proposes using laser printer toner in a bottle charged up to 10kV, but raises concerns about the amount of charge it can hold. They suggest increasing the charge by using a more highly charged material or smaller particle size, and also considering using a higher voltage.

i want to create a strong magnetic field with a rotating static electric charge

about a 100A would do. or 100C/s

that is a huge or very fast moving charge so i was thinking of using laser printer toner in a bottle and charge it up to 10kV

since the charge of a sphere is 4pi e a, it turns out C/V (per volume) is inverse proportional to the particle size. smaller particles more charge
the toner particle size is about 5e-6m and i can put about 85e6 in a sphere with a 0.1m radius (50% air 50% toner by volume)
so that translates into 7.4e-11 C/V and at 10kV that's 1e-6C very little

are the any errors with my thinking, is there a way to increase the charge by a few orders of magnitude??

There are a couple of ways to increase the charge by a few orders of magnitude. The first would be to use a more highly charged material, such as an ionized gas or a liquid electrolyte. This would allow for higher charge densities than can be achieved with toner particles. The second would be to use a smaller particle size. If you can reduce the particle size, you can increase the charge density. Additionally, you can also use a higher voltage to further increase the charge density.
 

1. What is a magnetic field from rotating static charge?

A magnetic field from rotating static charge is a type of electromagnetic field that is created by the rotation of charged particles, such as electrons, in a stationary position. This type of magnetic field is also known as a magnetic dipole field.

2. How is a magnetic field from rotating static charge created?

A magnetic field from rotating static charge is created when charged particles, such as electrons, rotate around an axis. This rotation causes the charged particles to create a circular motion, which results in a magnetic field being produced around the axis of rotation.

3. What is the relationship between magnetic field and rotating static charge?

The relationship between magnetic field and rotating static charge is that the rotation of charged particles creates a magnetic field. The strength and direction of the magnetic field depend on the speed and direction of the rotation of the charged particles.

4. How is a magnetic field from rotating static charge different from a magnetic field from a current-carrying wire?

The main difference between a magnetic field from rotating static charge and a magnetic field from a current-carrying wire is the source of the magnetic field. While a rotating static charge produces a magnetic field due to the rotation of charged particles, a current-carrying wire produces a magnetic field due to the flow of electric current.

5. What are the applications of a magnetic field from rotating static charge?

A magnetic field from rotating static charge has various applications in different fields such as physics, engineering, and medicine. It is used in particle accelerators, magnetic resonance imaging (MRI) machines, and in the production of electricity through generators.
