Experiments with magnetic levitation




Train that Frock coat (Maglev)

Description:

With this experiment one demonstrates that the equal poles are repelled.  We have a platform that floats on a pair of magnetic rails and thanks to a smooth impulse it is possible to be moved of a side the other.  He is very similar in concept to the MAGLEV that has been developed in Germany, Japan and France.

Construction:
The rails are two magnetic tapes each measures some 50cm of length and 1.5 cm with their North Pole aiming upwards.  Is placed to 1 cm of the melamine lamina or table edges of about 60 cm in length and 15 cm wide.

  Some are placed in the sides and to the ends wood laminae venesta (plywood) or cardboard., of about 6 cm of stop.  One of the sides can be made of plexiglas or acrylic plastic so that we see float to the train on rails.


The platform becomes of a piece of plastoform (plastic foam, telgopor) not very heavy of 13cm of width and some 20cm of length.  In lapar to you down a pair of magnetic tapes is placed that have the same length that the platform.  They are placed closely together of the edges.
In the ends of the platform and to both sides of the base magnets in the form of disc are placed. With the North face upwards, so that they work as means when platform arrives at one from the ends of the base and the magnets placed to the same height are repelled.  A piece of plastoform to both ends of the platform can be placed to glue magnets there.

In the edges of the platform sticky tape can be glued.  This allows that the train has a slippery surface to the sides.

The MAGNETS you can also obtain them of some electric home appliances, if you do not obtain tapes you can try with circular magnets obtained of little figures of pl [astico that stick to the refrigerators. The little figures were placed so that they simulate to be the passengers.

How it works:

We give to the train a empujoncito him for goes from a side to another one of the base.  You will see it float on rails.  The magnets in the ends avoid that the train crashes against the walls at the end of the base.

Conclusions:

This experiment serves as demonstration, it shows to us that the equal poles are repelled and unequal poles are attracted.
 
This it is a simplified diagram that shows to the areas of attraction and repulsion between magnets of the experiment.

Maglev trainTRAIN THAT FLOATS (MAGLEV)

With this experiment one demonstrates that the equal poles are repelled.  Wood train raft that floats on a pair of magnetic rails and thanks to a smooth impulse can be moved of a side the other.  He is very similar in concept to the MAGLEV that has been developed in Germany, Japan and France. All the elements except the wood base are provided to place magnetic rails. (Beam click in the photo for a greater image)
