Suspension Magnetic Pen Course Presentation

    Everyone knows that the maglev train uses the principle of 'like charges repel each other' to make the train capable of resisting the force of gravity, allowing the car to completely detach from the track and hover about 1 centimeter above the track, creating a near 'zero-height' space flight miracle. This experiment also uses this principle to make a pen hover. Isn't it amazing? Try and see if you can make the pen hover.

Experimental Objective: 1. To utilize the repulsive force between like poles of a magnet.
 2. Understand the simple principle of magnetic levitation
Experimental Cognition
 EVA: Pendulum Overall Support Structure
 Magnets: Magnets can generate magnetic fields and have the characteristic of attracting ferromagnetic materials such as iron, nickel, cobalt, and other metals.


Experimental steps:
1. Experiment preparation: understanding the experiment equipment: wooden frame, straw.

Experiment Report:
Magnetism: The parts of a magnet with strong magnetic properties are called the poles of the magnet. A magnet has a magnetic field surrounding it, and the interaction between magnets is mediated by this magnetic field. A magnet always has two poles, and a magnet that can rotate freely in a horizontal plane will always be found with one pole pointing south when it is stationary, and the other pole pointing north. The south-pointing pole is called the South Pole (S), and the north-pointing pole is called the North Pole (N). Like poles repel each other, while opposite poles attract each other.
