Make small electromagnetic swing

On Tuesday, a science teacher assign us to do homework - home to do a small production of science. Returned home, when I think I don't know what to do, my mother gave me a good suggestion: do a small swing, electromagnetic I saw mom, before is really interesting, I need to ask mother to help me to prepare the materials and tools, the materials they need to make their electromagnetic small swings are: two root length of about 20 cm thick wire enameled wire (or thick), about 1 meter long enameled wire, a battery, a piece of hard foam (or board), 2 wire, a magnet, the other is some wrapping paper, small toy doll (you can also use a paper doll), tape and pliers, knives and other tools.

Principle of swing

Swing setshas two cases:
Sitting in the swing, to push the other one, if only a push, and then just as a simple pendulum swinging back and forth, but because of air resistance, amplitude will be more and more small, but at the same time constant, this kind of situation with the vibration of the pendulum when cannot ignore air resistance; If pushed, swing when swing swinging back to swing a thrust, the amplitude of the swing may be the same or increase, then the vibration of the forced vibration.
The second case is that people usually stand on the swing, squat down and up to swing a driving force, make the Swing setswing, this also is forced vibration. As long as people squat down and set up a perfect balance of time, will swing swing higher and higher, on the contrary, the time to grasp well, you might swing.

Games, one on a multipoint rope swing, then bar at the bottom of the both sides, all of several people relative to one another, and the constant push bar, the top wooden wheel rotates.

Inflatable castle

Soft outdoor play equipment, combined with traditional inflatable bounce. Trampoline and climb the slide, and so on a variety of projects, increase the use of air circulation within the scientific principle, the balloon continuously cyclotron in the pipe, and imported polyether (transparent TPU), make the whole pipeline on the vision to look brand-new, too many things to see, more let the children enjoy the theme elevation like a the same feeling of weightlessness in space, and promote the growth of the brain, enhance the muscle strength of the muscles, enhance comprehensive sport ability, and can feel wonderful visual pleasure during exercise.
