Using magnets to make a small toy (in kind)

Use magnets to make a fun magnetic cart:

1, the preparation of materials: wooden strips, magnets, small pulleys, glue, ice-cream sticks, etc.

2, with wooden strips of wood glued a rectangular frame, and in the middle of the left part of the cross-bar and then glued

3, in the glued wooden frame of the corners of the four pulleys

4, glue the magnets Glue the magnets to the wooden strips

5, flip the frame over with the pulleys down, and glue the wooden strips with the glued magnets to the crossbar in the center of the frame.

6, glue the magnet to the ice-cream stick

7, the production is complete, the use of the same pole repulsive, the principle of opposites attract can make the car run.

Fun magnetic car principle:

Each magnet has a positive and negative poles, magnets around the existence of a magnetic field. When two magnets with the same pole close to each other, due to the magnetic field of mutual repulsion, the two magnets will be separated from each other;

When two magnets with different poles close to each other, under the action of the magnetic field, they will be attracted to a piece. In simple terms, the attraction and repulsion of magnets is due to the action of the magnetic field in the magnet. This is also known in physics as same poles repel and opposite poles attract.
