Quantum magnetic levitation applet
Instructions:
The 3D objects in the window can be rotated by holding the right mouse button and dragging.
the grey disc represents the chosen material. The black disc represents a magnetic field source and the red arrows represent the magnetic field.
In the dropdown menu the material can be changed.
With the temperature slider you can see how the superconductor will change it's properties as the temperature changes. Once the temperature gets below the critical temperature (Tc) of that specific material it will start superconducting and repel the magnetic field. This is called the meissnereffect. These superconductors fall in the category of type I superconductors.
Certain materials will only partially repel the magnetic field, this is called quantum locking. These superconductors are type II superconductors.
Non-superconducting materials will not repel the magnetic field at all.
With the Magnetic field slider you can adjust the magnetic field. As the magnetic field gets stronger the arrows representing it will increase in size.
Each superconductor has their own critical field (Hc). This is the amount of magnetic field they can endure before losing their superconducting properties. If the magnetic field gets above this value you will see that the superconductor no longer repels the magnetic field.
The graphs show the general shape of the resistance against the temperature, and the magnetic field against the repelled amount. They also include the critical temperature and critical field for each material. The graphs can be toggled on and off with the two checkboxes.
Below a list can be found of all materials and superconductors currently available for this applet. The underlined materials have a hyperlink installed. Upon clicking these materials you will be sent directly to their Wikipedia page.
