Science of Maglev
There is no doubt that principles of science have been tried and tested in the development of maglev vehicles.
What were your findings?What 3 scientific concepts do we see
working in magnetic levitation vehicles?
3 Scientific Concepts
The three main scientific concepts seen in maglev vehicles are:
Magnetic Fields
Friction
Aerodynamics
Magnets
Define magnetic fields.
Magnetic fields – A region around a magnetic material or a moving electric charge within which a force of magnetism acts.
Magnets
How do magnets work?
Magnets have two poles which either attract or repel.
RULE 1: Opposite poles attract
RULE 2: Same poles repel
Magnets
RULE 1: Opposite poles attract
RULE 2: Same poles repel
In a maglev train, the properties of magnets cause two forces.
Repel=LIFTAttracting=THRUST
Properties of Maglev Vehicles
ENERGY-EFFICIENT
Extremely Fast
Advantages of Maglev Vehicles!
Friction
Define friction.
Friction – The resistance that one surface or object encounters when moving over another.
Friction
Think about this: Is friction involved with maglev vehicles?◦NO!
Properties of Maglev Vehicles
Energy-efficient
EXTREMELY FAST
Advantages of Maglev Vehicles!
Aerodynamics
Define aerodynamics.
Aerodynamics – The study of the properties of moving air, especially the interaction of the air and the solid bodies moving through it.
Think of a sports car…
Aerodynamics
Think about this: Are maglev trains designed to be aerodynamic?◦YES!
What makes them aerodynamic?◦Their shape!
Properties of Maglev Vehicles
ENERGY-EFFICIENT
EXTREMELY FAST
Advantages of Maglev Vehicles!
the BIG IDEA
Science: Magnets, friction, aerodynamics
Allow for:Energy-efficiency and extremely fast speed
Ultimately lead to:Advantages of Maglev Transportation
YOUR TURN!!!
Now you are going to apply your knowledge to watch these scientific principles at work!
In your groups, you will take turns travelling to 3 stations:◦Magnetic fields◦Friction◦Aerodynamics
You will complete an activity at each station!
