4PCS Magnetic Stick Flexible Rod And 4PCS Steel Ball Assembly Education Children Toys

The models shown above are amazing, right? Once you make the magnets get the max. magnetic force, the basic condition, then it is much easier for you to building the models as pictures. Please see Picture A and Picture B. In these two pictures, the triangles are the same. Three angles of the triangle in the Picture A cannot attract steel balls, while two angles of the triangle in the Picture B can attract steel balls. Why? Because in Picture A, the magnetic circuit of the triangle is balanced and reach its max. magnetic force, while the triangle in Picture B is not, which make the steel balls magnetized. Therefore, triangle A is firmer than triangle B. Most of people know the basic rule: the same polarity will repel each other, while those of different polarity will attract each other. If you want to get the max. magnetic force, you have to make sure the magnetic circuit is balanced. Balanced magnetic circuit means each connection has different polarity, also the magnetic models are firmest. Using imbalanced magnetic circuit, you can build more interesting dynamic models.    Items: 01. Steel Balls   02. Straight Magnetic Rods   03.
