Answer test questions?
Hey, I have a physics test tomorrow and wanted to know if someone could answer these questions for me because I can't find them anywhere (not in the book, notebook or google) 1. What is the electrical current 2. What is the difference between +pole and -pole 3. "Large electrical resistance" What does/is that 4….
Current strength?
Bygaba88
A=pi*r^2 = pi*(0.0025m)^2 = 0.000019625m^2 * 0.01m/s = 0.00000019625 m^3/s = 0.2cm^3/s Answer 1 ?
Physics fine beam tube evaluation?
ByTadeo717
Hello, I'm writing my physics exam in a few days on the topic of narrow beam tubes. I know the basic principle because it was covered in the last exam. My question is, what can I learn to prepare for the evaluation? My teacher wrote the following: Fine-beam tube: Here, you need to fundamentally understand…

World formula developed by me?
Could my world formula close the gap in current physics? Hello everyone, I have developed a universal formula based on the principles of resonance, vibration, and the Fibonacci sequence, which describes the universe in a comprehensive context. Here are the key points of my considerations: 1. The word as a wave – creation through energy…
What do you think is behind the 5th and 6th dimensions?
Byvreezer
Now that more and more scientists have embraced quantum physics, and it is now recognized and considered a serious worldview, what will these "new" dimensions look like, where mind prevails over matter, where we leave the limits of all physical laws and even linear time behind us? What do you think the 5th and 6th…
The iron magnet model is a model that is used to explain the magnetic properties of iron and other magnetic materials. It describes how the magnetic moments of the atoms in the material are oriented and how they influence each other.
The model assumes that each iron atom is a small magnet that has a magnetic moment. In an unmagnetized material, these magnetic moments are arranged in random orientation, so that the total magnetic field of the material is zero. When the material is magnetized, the magnetic moments of the atoms are aligned in a specific direction, which leads to an overall magnetic field.
The iron-magnet model also explains why iron and other magnetic materials lose their magnetic properties when heated. By heating, the magnetic moments of the atoms are oriented more randomly and the material loses its magnetic properties.
There are also other models, such as the domain model, which describes how the magnetic moments align in larger areas in the material and how the magnetic domains influence each other.
