Science Entry:
For Science we are studying the book "Electricity and Magnetism". Mr.S, our teacher, assigned us a science project in which we do eight to ten minutes video. I am in group with Elena and Stefania.
Our topic is magnetism. In our video we do several experiments and we try to explain how magnets work and how they are made.
Each magnet has it's negative and positive pole . Each negative pole attracts it's own positive pole. If you put two negative poles, they will repel. Instead a negative and a positive pole attract. Magnets have their own magnetic field that are mapped by the magnetic field lines. Magnetic field lines spread out from one pole, curve around a magnet, and return to the other pole. A cluster of billions of atoms that all have magnetic fields that are lined up in the same way is known as a magnetic domain . Every magnet has it's magnetic domain alined to attach to ferromagnetic things.
