Seminar on Magnetic levitation and its applicatonRahul Shaw
Magnetic levitation is the use of magnetic fields to levitate a (usually) metallic object. Manipulating magnetic fields and controlling their forces can levitate an object.
In this process an object is suspended above another with no other support but magnetic fields.
The electromagnetic force is used to counteract the effects of gravitation. But it has also been proved that it is not possible to levitate using static, macroscopic, `classical' electromagnetic fields.
The forces acting on an object in any combination of gravitational, electrostatic, and magnetostatic fields will make the object's position unstable.
The reason a permanent magnet suspended above another magnet is unstable is because the levitated magnet will easily overturn and the force will become attractive. If the levitated magnet is rotated, the gyroscopic forces can prevent the magnet from overturning.
Several possibilities exist to make levitation viable.
It is possible to levitate superconductors and other diamagnetic materials, which magnetise in the opposite sense to a magnetic field in which they are placed.
A superconductor is perfectly diamagnetic which means it expels a magnetic field (Meissner-Ochsenfeld effect). Other diamagnetic materials are commonplace and can also be levitated in a magnetic field if it is strong enough.Diamagnetism is a very weak form of magnetism that is only exhibited in the presence of an external magnetic field.
The induced magnetic moment is very small and in a direction opposite to that of the applied field. When placed between the poles of a strong electromagnet, diamagnetic materials are attracted towards regions where the magnetic field is weak.
Diamagnetism can be used to levitate light pieces of pyrolytic graphite or bismuth above a moderately strong permanent magnet. As water is predominantly diamagnetic, this property has been used to levitate water droplets and even live animals, such as a grasshopper and a frog.
Superconductors are perfect diamagnets and when placed in an external magnetic field expel the field lines from their interiors (better than a diamagnet). The magnet is held at a fixed distance from the superconductor or vice versa. This is the principle in place behind EDS (electrodynamic suspension) maglev trains. The EDS system relies on superconducting magnets.
A maglev is a train, which is suspended in air above the track, and propelled forward using magnetism. Because of the lack of physical contact between the track and vehicle, the only friction is that between the carriages and air. So maglev trains can travel at very high speeds (650 km/h) with reasonable energy consumption and noise levels

Maglev (derived from magnetic levitation) is a transport method that uses magnetic levitation to move vehicles without touching the ground. With maglev, a vehicle travels along a guideway using magnets to create both lift and propulsion, thereby reducing friction and allowing higher speeds.Maglev trains move more smoothly and more quietly than
wheeled mass transit systems. They are relatively unaffected by
weather. The power needed for levitation is typically not a large percentage of its overall energy consumption;most goes to overcome air resistance (drag), as with other highspeed transport. Maglev trains hold the speed record for rail transportation

Maglev Trains- Train That Fly on the AirOnkar Pawar
Maglev is short for Magnetic Levitation in which trains float on a guide way using the principle of magnetic repulsion. Each magnet has two poles. Now if you play with two magnets, you'll realize that opposite poles attract, whereas similar poles repel. This repulsive property of magnets is used in Maglev trains. However, instead of using permanent magnets, the principle of electromagnetism is used to create strong and large temporary magnets. When an electric current is passed through a coil of wire, magnetic field is generated around the coil according to Faraday's laws.

Kubernetes & AI - Beauty and the Beast !?! @KCD Istanbul 2024Tobias Schneck
As AI technology is pushing into IT I was wondering myself, as an “infrastructure container kubernetes guy”, how get this fancy AI technology get managed from an infrastructure operational view? Is it possible to apply our lovely cloud native principals as well? What benefit’s both technologies could bring to each other?
Let me take this questions and provide you a short journey through existing deployment models and use cases for AI software. On practical examples, we discuss what cloud/on-premise strategy we may need for applying it to our own infrastructure to get it to work from an enterprise perspective. I want to give an overview about infrastructure requirements and technologies, what could be beneficial or limiting your AI use cases in an enterprise environment. An interactive Demo will give you some insides, what approaches I got already working for real.

Neuro-symbolic is not enough, we need neuro-*semantic*Frank van Harmelen
Neuro-symbolic (NeSy) AI is on the rise. However, simply machine learning on just any symbolic structure is not sufficient to really harvest the gains of NeSy. These will only be gained when the symbolic structures have an actual semantics. I give an operational definition of semantics as “predictable inference”.
All of this illustrated with link prediction over knowledge graphs, but the argument is general.
3. Magnetic levitation is a method by which an object is
suspended with no support other than magnetic fields.
Magnetic pressure is used to counter act the effects of
gravitational forces.
The magnetic pressure of a magnetic field can be calculated
by : Pmag=B2/2μ0 .
4. Diamagnetic materials are the substances which repels the
magnetic lines of force in a magnetic field.
Superconductors may be considered perfect diamagnets.
(μr = 0).
A magnet levitating above a high temperature,
super conductor, cooled with liquid nitrogen.
Persistent electric current flows on the surface
of the superconductor, acting to exclude the
magnetic field of the magnet .
5. A new transportation mode has occurred that can clearly
compete with planes in both speed and safety. They are
called MAGLEV TRAINS.
Magnetic levitation principle can also be used in wind
turbines and we can call it as MAGLEV WIND TURBINES
6. This is a vehicle that can be
suspended and propelled on
a guidance track made with
magnets.
The MAGLEV trains are
known to have more speed,
smoothness and less sound.
The trains are also
aerodynamically designed
which enables them to
reach great speeds like
300 miles/hour
7. The train will be floating
about 10mm above the
magnetic guiding track.
In MAGLEV trains, the power
to propel the train is
provided by the magnetic
fields created by the electric
coils kept in the guidance
tracks.
8. There are two kinds of
wind turbine, which are
HAWT ,VAWT .
Guangzhou Energy
Research Institute
under China’s
Academy of Science
introduced magnetic
levitation principle in
wind turbine.
10. Magnetic levitation is the phenomenon of rising up a material
with the help of superconductors and the other magnetic
materials.
The one of the remarkable application of the magnetic
levitation is maglev train which travels with a velocity of 160
m/s.
The magnetic levitated wind turbine has high efficiency and
can produce large amount of wind power.
The magnetic control system is one of the rising phenomenon
in modern technology which is application of magnetic
levitation.
