Levitating Steel Sphere: Engineering Questions Answered

[cd27]

here are some questions i need answered:

How much energy (electricity/magnetism) would it take to make a pure steel metal sphere with a diameter of about four inches levitate?

2. With question one answered, we may now ask, what type of device would need to be used to make the electromagnet change its pressure of electromagnetic force when the device is tilted?

3. To account with question two, what type of design would an electromagnet need in order to perform its function (to levitate a metal sphere with a radius of two inches even when tilted)?

4. About how much electrostatic electricity would be needed to make a complete wall between the inner sphere’s outside wall and the inside wall of the outer sphere, given that there is an approximate ½ to 1 inch space between the inner solid sphere and the hollow outer sphere.

5. Once the inner sphere is somehow levitated, how far out will these magnetic fields erupt from the device? With that said, how thick should the outer glass covering (perhaps we could use lead, or some other substance which could keep the field from leaving the device and block it from the computer chips on the outside-glass was just an idea to extend away from the field, but if there is a substance that could repel a magnetic field, it would be much more sufficient) have to be to keep the magnetic field from interfering with the computer chip, or worse, deleting the information stored on it.

6. If wires from the computer chips were to be inserted into the empty space (where the static electricity would be), could it affect the chip with data loss or damage?

7. Would the four prongs (which will inserted into the bottom four corners of the device) be able to be inserted into the empty field to produce the static field and would these prongs be able to extract energy from an external generator for initial power without damage?

8. How large of a generator would be needed to run this entire device?

In the first part, the mass of the metal sphere is just density x volume.

One needs to determine the magnetic field and then current (in an electromagnet) to levitate the weight - mg.

For your "device" you may want to do some research and look into work that is being done with magnetic field bearings. It sounds like you are wanting to do something similar.

Is this all in relation to the threads you've had locked previously? Just curious.

Sure looks similar...:uhh:

 

[cd27]

i will most definitely look up the magnetic field bearings...thank you for your help.

i did a google search on that...i couldn't find a single thing...any ideas?

So, let me get this straight: you don't know the first thing about electricity/magnetism, but for some reason you think it can be used to create a perpetual motion machine. But since you don't know the first thing about electricity/magnetism, you want us to design it for you? :uhh:

cd27, get the message: stop wasting your time and ours, set aside your pmm ideas for a while, andlearn how electricity/magnetism work. After you have learned about electricity/magnetism (and, perhaps, some engineering), then revisit your pmm idea. I suspect you will instantly realize why it is a rediculous idea, a pointless pursuit, and a waste of your time and ours. In the meantime, we will not play the enablers for your addiction here.
