How does Inductrack work?
The Inductrack concept is a passive magnetic levitation system for moving objects that employs special arrays of permanent magnets in the moving object. The magnetic field from these arrays induces currents in the “track” that, by interacting with the magnetic field, produce strong lifting forces.
Is passive magnetic levitation possible?
Passive magnetic bearings (PMB) achieve contact-free levitation of an object by permanent magnetic attractive or repulsive forces. Depending on the configuration, stabilization in radial, axial and tilt direction are possible.
How does electrodynamic suspension work?
Electrodynamic suspension (EDS) is a form of magnetic levitation in which there are conductors which are exposed to time-varying magnetic fields. This induces eddy currents in the conductors that creates a repulsive magnetic field which holds the two objects apart.
How does a Halbach array work?
A Halbach array is arrangement of permanent magnets that creates a stronger field on one side while reducing the field on the other side to near zero. This is accomplished by orienting the magnets so that their poles are out of phase, typically by 90 degrees.
How does magnetism keep the cars suspended floating?
Magnetic field generated, repels the gravitational force created by earth and allows the floating island to remain suspended in air. The island will keep rotating or spinning its platform which in turn will be responsible to generate energy required to maintain stability while on suspension.
How much does magnetic levitation cost?
MagLev Costs At only 20 miles long, that is an incredible amount of capital cost. At that cost, it is about $60 million dollars per mile of track.
Does the Hyperloop use magnets?
The hyperloop pod is equipped with Halbach arrays on the bottom. Halbach arrays are magnets in a special configuration, focusing the magnetic field towards the track.
What is the difference between electromagnetic suspension and electrodynamic suspension?
electromagnetic suspension (EMS) uses the attractive magnetic force of a magnet beneath a rail to lift the train up. electrodynamic suspension (EDS) uses a repulsive force between two magnetic fields to push the train away from the rail.
How much stronger is a Halbach array?
The Halbach array pulled (on the strong side) with about 72 lb of force. While strong, a set of 5 magnets arranged with all their north poles facing up is slightly stronger, at 77 lb.
What is the value of 1 tesla?
One tesla is equivalent to: 10,000 (or 104) G (Gauss), used in the CGS system. Thus, 10 kG = 1 T (tesla), and 1 G = 10−4 T = 100 μT (microtesla). 1,000,000,000 (or 109) γ (gamma), used in geophysics.
Is the bullet train maglev?
Bullet Trains vs Maglev Trains Though both are insanely fast trains, the Maglev can be thought of as a step up from the bullet. While bullet trains travel at speeds of 320kph, Maglev trains are anticipated to travel at speeds well over 500kph.
What is the Inductrack system?
The Inductrack system optimizes levitation efficiency, using permanent magnets and a passive “track.” • Special arrays (Halbach arrays) of permanent magnets are employed, mounted on “bogies” underneath the car.
Is the Inductrack Maglev system an economic alternative to maglev?
• The Inductrack maglev system, employing simple arrays of permanent magnets, may offer an economic alternative to existing maglev systems.
What is the Inductrack II configuration?
• Better to satisfy urban (moderate speed) applications we have developed the Inductrack II configuration, which greatly reduces electromagnetic drag forces at urban speeds (relative to Inductrack I, which is more suitable for high-speed applications). Lock./39
What is the lift-to-drag ratio of the Inductrack?
The Lift-to-drag ratio of the Inductrack increases linearly with speed, and can exceed 200 at maglev train speeds Lock./19 0 100 200 300 400 500 0 50 100 150 200 250 300 350 400 450 Lift/Drag Ratio for Inductrack and for Conducting Plate Speed (km/hr)
