How to play the hovering saucer? 15

1. Hold both ends of the bracket, and after the UFO is balanced and rotated, slowly lift the UFO to a height of about 3 to 4 cm, and if the UFO weight is appropriate, it will automatically jump up and enter the suspension state; Potato trembling.

2. If the flying saucer rotates unsteadily when the rotation starts, one end of the supporting piece can be lifted to form an inclination angle, and the flying saucer rotation will gradually stabilize;

3. If the flying saucer shakes too much when it is held up, it will be sunk quickly, and the flying saucer can automatically use the change of magnetic field strength to find the center and achieve rotational stability, and then slowly hold it to the suspended position;

4. If the flying saucer rotates more stably before entering the suspension, then after entering the suspension, the more stable the flying float will be, and the longer the time will fail.

1. Use the transmitter box of the radio as the base, and the box with the ring is used to hold the magnet and sensor. Drill holes on the surface of each box, pass through the wires, install the power button, set the height button, and install the LED indicator;

2. Connect the coil of the electromagnet to the power supply line, and install it into the noisy ring box, pay attention to ensure that the installation of each power cord is correct, and after the installation is completed, add the permanent magnet to the ring;

3. Glue the electromagnetic inductor to a piece of transparent glass and connect the power cord, which also ensures that the wheels of each power cord are connected correctly;

4. Install the control elements on the base, including the installation of microcontroller, power supply, LED indicator and other parts;

5. According to the size range of the magnetic force, the weight of the object, and the strength of the magnet in the object, find out the appropriate shape and size of the object, and make a suitable floating object.

Here's how to play the Hoverball:

1. Hold both ends of the bracket, wait for the UFO to balance and rotate, slowly lift the UFO to a height of about 3-4cm, and if the UFO weight is appropriate, it will automatically jump up and enter the suspension state.

2. If the flying saucer rotates unsteadily when the rotation starts, one end of the supporting piece can be lifted to form an inclination angle, and the flying saucer rotation will gradually stabilize;

3. If the flying saucer shakes too much when it is held up, it will be sunk quickly, and the flying saucer can automatically use the change of magnetic field strength to find the center and achieve rotational stability, and then slowly hold it to the suspended position;

4. If the flying saucer rotates more stably before entering the suspension, then after entering the suspension, the more stable the flying float and the longer the time.

The principle of levitating a small ball

Aerodynamics and vortex effects are utilized. When the air flow through the sphere, a vortex is formed, which creates an area of low pressure below the sphere, causing the sphere to experience upward buoyancy. The gravity of the ball itself pulls the ball downwards and eventually reaches a state of equilibrium, thus achieving levitation.

In addition to aerodynamics and vortex effect, there are some other principles that can also realize the suspension of small balls, such as magnetic levitation, electric levitation, etc.

In addition to aerodynamics and vortex effects, there are some other principles that can also be used to levitate small balls, such as magnetic levitation, electric levitation, etc. Overall, levitating spheres are a very interesting physical phenomenon that involves the application of a variety of physical principles. For physics enthusiasts, the principle of the tarsity ball of the cantilever beam can be deepened through experiments or theoretical research.

Magnetic suspension top.

No electricity required. There is no fulcrum.

Anti-gravity floating.

The product uses a variety of physics knowledge to synthesize the law of conservation of magnetic field; Elaborate rehearsals, a moment of surprise, flying saucers are suspended in the air, non-stop. There is absolutely no need for electricity, no fulcrum.

High-tech educational toys with magnetic flying saucers.

This toy is made of permanent magnet material through high-tech treatment, it adopts the same principle as the world's most advanced Shanghai maglev train, and is a good teaching aid for teachers to use in the classroom.

Principle analysis: when the flying saucer is suspended, the resultant force is zero, and the expression g f 0, that is, f and g are equal in size, opposite in direction, and in the same straight line. In addition, it also involves air resistance, eddy current friction force, the principle of energy conservation, the earth's magnetic field, the gyro-fixed axis principle, etc.

Principle of operation: the magnetic field force f on the suspension point of the flying saucer is a fixed value, and the size of g is increased or decreased accordingly by the adjusting piece, so that g g1 g2 (g1 is the weight of the flying saucer, and g2 is the weight of the gravity adjustment piece. ）

After you understand the physics of the flying saucer, through careful practice, the flying saucer floats in the air without electricity and has no fulcrum, which is endlessly fun.

Site selection: The magnetic UFO must be placed in a stable place on the table that will not shake, away from other objects with ferromagnetic reactions.

Operation Guide: (with instructions).

After mastering the skills of UFO rotation, weight adjustment, and chassis magnetic field angle adjustment, you can enter the magical anti-gravity suspension world, first put the pallet on the chassis, rotate the UFO in its central position, and use the pallet to slowly lift the UFO to the height of about 3 4cm of the chassis, and the UFO will automatically leave the chassis and float upwards to the balance point.

Thinking & Puzzle.

Test the ability to balance and coordinate, quickly find the center position of the magnetic field and rotate it.

Test patience and perseverance with precise adjustment of magnetic field balance and saucer weight.

Test the hands-on ability to rotate the flying saucer more smoothly and quickly and put it into a floating state.

Improve analytical skills and imagination:

1.What are the physical principles of a suspended flying saucer? What forces are applied to a flying saucer when it is suspended?

2.Why are the gravity adjustment tabs required for the suspension of flying saucers at different locations or at different times in the same place are different?

3.What role does the rotation of a flying saucer play in its suspension process? What are some ways to make the suspension last longer?
