Electromagnet stick is the key to build a flying disk

Click For Summary

Discussion Overview

The discussion revolves around the concept of using an electromagnet stick to create a flying disk, exploring the feasibility of such a design, its aerodynamic properties, and the role of Earth's magnetic field in maintaining its position. The conversation touches on theoretical and conceptual aspects of electromagnetism and aerodynamics.

Discussion Character

  • Exploratory
  • Debate/contested
  • Conceptual clarification

Main Points Raised

  • One participant suggests that controlling the input voltage of an electromagnet stick can maintain its orientation regardless of the disk's rotation speed.
  • Another participant argues that a flying disk cannot achieve flight without support, referencing maglev trains as an existing technology that utilizes magnetic support.
  • A participant proposes that the disk can fly due to its wing-like structure and that rotation may provide better aerodynamics than traditional wings.
  • Concerns are raised about the strength of Earth's magnetic field being insufficient to support a heavy magnet in position.
  • Some participants question whether a stronger magnet could maintain its position against gravitational forces, but others counter that increasing magnet strength does not lead to better orientation with Earth's magnetic poles.

Areas of Agreement / Disagreement

Participants express differing views on the feasibility of the flying disk concept, particularly regarding the role of Earth's magnetic field and the effectiveness of electromagnets in achieving flight. No consensus is reached on the viability of the proposed design.

Contextual Notes

Limitations include assumptions about the strength of magnetic fields, the mechanics of flight, and the dependence on specific configurations of the proposed system. The discussion does not resolve the mathematical or physical principles involved.

The electromagnet stick always head N/s, no matter how fast the rotation of the shell of the disk is, you just need to control the input voltage of it, and it will not get heavy if the Magnetic stronger. I think the input higher voltage can make it head with power and hard to change the direction and return to the N/S quickly.

In that case, fix a jet motor on the end of electromagnet stick, the flying disk will move forward easily while rotation.

Sorry for my bad english.

Can you provide an image showing your concept?

No, you cannot make a disk flying without any support, like magnets on the ground to keep it in position. With support, look up the concept of maglev trains: It already exists and you can move these trains easily.
 
I need the Earth poles to keep its position, it can fly because the disk is wing. I think rotating is a better aerodynamic than the traditional wing

The magnetic field of the Earth is nowhere near strong enough, by orders of magnitude, to keep a magnet in position. Did you ever wonder why the needles of compasses weigh less than a gram and are balanced on the tip of a pin?
 
I guess the magnet of the needle is not strong enough to reposition itself if heavy, in that way it may go back but will too slow. I want to ask if the magnet is very strong may it be keep the position with power?

No. Otherwise every powerful magnet we use would try to rip itself from its foundations to orient itself N-S. They don't.

Sorry, I couldn't understand English much, please say it clearly again let me know about my fault...

No. Making the magnet stronger will not make it more prone to orienting itself with the Earth's magnetic poles.
