The magnet is placed over a super conducting material. Because super conductors conduct electricity with zero resistance, it repels the magnet making it float. The super conductor is usually a piece of YBa2Cu3O7 cooled to below 92 degrees kelvin. At this temperature, the substance changes state from a solid to a bose-einstein condensate and is a super conductor.
What else can I help you with?
How many types of magnets are there?
none
What are the types of magnets?
Ferro-magnets, permanent magnets, temporary magnets, and electromagnets. Ferro-magnets are magnets that are magnetic at a higher temperature than room temperature. do not quote me on that. permanent magnets are magnets that are always magnets, they are the kinds you use a lot. Temporary magnets are things that are magnetic in an extrenal magnetic field. Last but not least, electromagnets. Electromagnets are coils of wire around a cobalt, nickel, or iron. When ou run electricity through the wire, the core and wire become magnetic.
Are magnets metal?
No, magnets are not metal. Magnets are objects that produce a magnetic field, which can attract or repel certain types of metals, but they are typically made from materials like iron, nickel, or cobalt.
Why don't we use permanent magnets in electric bell?
Permanent magnets do not provide the flexibility to control the strength of the magnetic field, which is essential for regulating the vibration of the armature in an electric bell. Electromagnets, on the other hand, allow for the magnetic field strength to be easily adjusted by varying the current flowing through the wire, enabling precise control over the bell's operation.
Do magnets attract all metals?
No. Magnets do not attract gold, silver, aluminum, brass, copper or lead. Magnets will attract nickel and iron or steel.
How do you make two magnets float?
By balancing apposite poles
How can you make objects float in mid air with magnets?
eat the magnets. then look at an object, then it'll float. don't listen to him just experiment with magnets and metallic spheres and circles of magnets, make this project your own don't copy someones work that's plagiarising and you will have alot more fun making your own experiment e-mail me @ jkraftj@yahoo.com
What magnet produces maximum rotation and torque- radial ring or diametric ring magnets?
Diametric ring magnets typically produce more rotation and torque compared to radial ring magnets. This is because the magnetic field lines of diametrically magnetized rings pass through the center of the ring, providing a more direct and efficient coupling with the rotating element.
Can you make something float in mid air with magnets?
yes it can be done with a powerful enough magnets put them on the object and floor with the same poles facing each other and the will float Ive been working with magnets for a science project.Get two magnets andhave them facing the oppisite poles.Cover up the edge of a magnet with a repolsive material.Then put the magnet you want to float on top.Or you can buy Magi UFO on ebay.It a floating magnet.Its really cool:)
How you could use magnets to make a small object to appear to float in air?
If you hold two magnets in your hand one below the other so that the north side of one magnet is facing north of the other and vice-versa, then place a metallic entity between these two magnets then it will appear to float provided distance between magnets and their force is equal.
Is the ring sink or float in oil?
It sinks
What is the circular float called on a boat?
Life ring.
What type of train uses magnets?
The maglev train floats over its track using an electromagnet. Maglev trains have managed speeds in excess of 370mph. A model of the maglev train uses two permanent magnets to get the model to float over the track.Describe how the magnets must be arranged to get the model Maglev Train to float.
What are the different shapes of magnets?
Horseshoe, Bar, U, Ring, Circle, etc.
How do you make a pencil float in the air?
You can make a pencil float in the air by using powerful magnets. Place a magnet above and below the pencil to create a magnetic field that counteracts gravity and lifts the pencil. Be cautious when working with magnets to avoid any accidents or damage.
How many magnets to float 400 pounds in mid air?
It is not a question of how many magnets you need, one would do; but how strong the field is and how strongly it attracts the 400 pound object.
Ultra simple way to make coins float on magnets?
If you hold two magnets in your hand one below the other so that the north side of one magnet is facing north of the other and vice-versa, then place a metallic entity between these two magnets then it will appear to float provided distance between magnets and their force is equal.
