I'm in the process of designing a deployable structure, however to replicate zero gravity deployment I am exploring options to remove friction. Therefore I am looking at the possibility of levitation through magnets. I've seen that been done, really interesting however as you've said not practical in my case.DarkBabylon said:Problem with this one the magnet is underneath (or is it above later in the video?) and is at a very cold cold temperature.
This is called Flux pinning, and it is not just levitation it locks. What exactly is the problem? to have a pin you need certain materials and loads of energy output from the disc itself.
There is a different concept where the magnets are on the board in a quad-copter configuration, but is limited to be used only over conductive surfaces. There is/was one built by Hendo but is unstable, and very heavy making it hard to control and it wasn't a DIY hack. (also very noisy)
Either way it would be quite a bill to try and prototyping it. Unless there was another way to make a overboard I am unaware of.
You could construct a surface made up of tens of thousands of electromagnets. Arrange for electronics to sense the location of your hoverboard and cause current to go to just those solenoids directly beneath and around it so they repel the permanent magnets embedded in the hoverboard.Brendan Staley said:I was hoping to create a magnetic surface in which i could have an opposing magnet to create a repel force? Just wondering if creating that sheet is possible?
The board works by utilizing the principle of magnetic levitation, also known as maglev. This involves using strong electromagnets to create a magnetic field that repels against the Earth's magnetic field, causing the board to levitate.
The main materials needed are a strong power source, electromagnets, conductive materials, and a control system. The power source is typically a battery or power supply, while the electromagnets can be made from copper wire and iron cores. Conductive materials, such as aluminum or copper, are used to create the board's surface, and the control system is responsible for managing the strength and direction of the magnetic field.
The weight capacity of the board depends on several factors, such as the strength of the electromagnets and the size of the board. Generally, a small electromagnetic board can support up to a few pounds, while larger ones can support heavier weights. However, the design and construction of the board also play a significant role in its weight capacity.
As with any scientific experiment, safety precautions should be taken when creating and using an electromagnetic board for levitation. The strong magnetic fields generated can interfere with electronic devices and pacemakers, so it's essential to keep them away from the board. Additionally, the board's construction should be sturdy and stable to prevent accidents or injuries.
Yes, there have been successful attempts at using maglev technology for transportation, such as the maglev trains in Japan and China. However, creating a large-scale electromagnetic board for levitation for personal transportation would require advanced technology and significant resources, so it is not currently a viable option for most people.
