Can Static energy generate magnetic field?

In summary, static energy can generate an electric field but not a magnetic field unless there is relative motion involved. To measure the strength of the static energy, one can use a charged ball on a string or a hall probe. The type of charge generated on the surface of the ball depends on the type of generator being used.

Referring to following image, static energy is generated, do we detect any magnetic field around this area? If we only get pure positive or negative charge on stable object, will it generate any magnetic field?
On the other hands, is there any digital device to measure the strength of static energy?
Does anyone have any suggestions?
Thanks in advance for any suggestions

In classical E&M magnetic fields are created by moving charges or time varying E fields, so if your source charges are stationary there should just be an E field.
you could use a charged ball on a string like a pendulum to measure the E field.
Or if you want to measure B fields you would use a hall probe.
Here they calculate the charge on a ball in an E field.

Do you know what kind of charges on the surface of the ball? Positive or Negative charges?
Thanks you very much for any suggestions

If there is no moving charge or changing field there is not likely to be detected by a stationery object like a compass. But it seems that electric and magnetism can easily transform from one to another in different reference frames.

no, if the observer is stationary with respect to the apparatus,

yes, if the obserber is in relative motion with respect to the apparatus.

I see, no movement, no magnetic field,
Does anyone know about this device on what kind of charges generate on the surface of the ball? Positive or Negative charges? I would like to purchase one, where can I purchase a small one?
Thanks you very much for any suggestions

You can have generators which create negative charges on the surface and others which will create positive charges, you'd have to check with whoever you're buying it from :)
 

1. Can static energy generate a magnetic field?

Yes, static energy is capable of generating a magnetic field.

2. How does static energy generate a magnetic field?

Static energy, also known as electrostatic energy, is created when there is an imbalance of electric charges. This imbalance of charges creates an electric field, and when the charges are in motion, it also creates a magnetic field. This is known as the electromagnetic field.

3. Is the magnetic field generated by static energy strong enough to be useful?

Yes, the strength of the magnetic field generated by static energy depends on the amount of static energy present. In certain situations, it can be strong enough to be useful, such as in particle accelerators and certain types of motors.

4. How is static energy used to generate a magnetic field in technology?

In technology, static energy can be used to create a magnetic field in various ways. For example, in a cathode ray tube, static energy is used to deflect the electron beam, creating the image on the screen. In certain types of generators, static energy is used to produce a magnetic field that is then used to generate electricity.

5. Are there any dangers associated with static energy and its magnetic field?

Yes, static energy can pose a danger if not handled properly. A strong magnetic field can interfere with electronic devices and cause disruptions. Additionally, in certain situations, a discharge of static energy can be hazardous to human health. It is important to follow proper safety precautions when working with static energy and its magnetic field.
