Magnetism of matter Materials can be divided into three types: ferromagnetic, paramagnetic, and diamagnetic, depending on how they react to an external magnetic field. Ferromagnetic In ferromagnetic materials, each atom acts like a magnet. In ferromagnetic … more
What is the difference between a magnet and an electromagnet? Let’s assume there is a small container you can’t see inside. There is a magnetic field around this container that can attract iron. Then, can you … more
Magnetic Force The magnetic force acts between two magnetic objects. Gravity only pulls, but magnetic force also has the force to push, including pulling force. When the different poles of the magnet are close, they pull … more
Why does the night sky look dark? It’s dark at night. This seems obvious, but you’ll find something strange if you think about it a little. Shouldn’t the universe be bright if the night sky is … more
* By adjusting the temperature of the thermometer, you can observe the state of the water corresponding to the temperature. * Depending on the temperature of the water, some water molecules may evaporate. State of matter … more
Vacuum Jar A vacuum jar(or vacuum sealer, vacuum container) is a container that can remove air using a pump. Originally, vacuum jars were made as kitchen utensils to help meat soak in seasoning. Now, they are … more
* After setting the small object’s mass, position, initial velocity, and initial direction of movement, turn on the ‘Run’ checkbox to start the simulation. * The gravitational constant of the celestial body were assumed to be … more
CRT TV CRT TV is an image-receiving device that uses cathode rays. It was widely used as a TV receiver until the mid-2000s. However, it had the disadvantage of being large and heavy. Afterward, it gradually … more
x y Vx Vy * The mass and gravitational constant of the celestial body were each assumed to be ‘1’. * You can edit the position and speed of each celestial body while not running. * … more
The ideal gas equation is a formula that expresses the law of the relationship between pressure, volume, number, and temperature of ideal gases. With this simple equation, you can calculate the remaining variables you don’t know. … more
This simulation supports multitouch. Nature of gas Since the gas can not be seen or touched, a little imagination is needed to understand the ‘nature of the gas.’ In most everyday life, people often do not … more
