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!
