WebPerkakas Ilustrasi Teori Dinamo. Dalam geofisika, teori dinamo merupakan teori yang mengusulkan mekanisme penghasilan medan magnet oleh Bumi, planet lain, atau bintang. Teori ini mendeskripsikan proses saat cairan yang berotasi, berkoveksi, dan konduktif secara elektrik dapat menghasilkan medan magnet dalam waktu yang lama. In physics, the dynamo theory proposes a mechanism by which a celestial body such as Earth or a star generates a magnetic field. The dynamo theory describes the process through which a rotating, convecting, and electrically conducting fluid can maintain a magnetic field over astronomical time scales. A … See more When William Gilbert published de Magnete in 1600, he concluded that the Earth is magnetic and proposed the first hypothesis for the origin of this magnetism: permanent magnetism such as that found in See more Dynamo theory describes the process through which a rotating, convecting, and electrically conducting fluid acts to maintain a magnetic field. This theory is used to explain the presence of anomalously long-lived magnetic fields in astrophysical … See more Broadly, models of the geodynamo attempt to produce magnetic fields consistent with observed data given certain conditions … See more • Stanislav I. Braginsky, research geophysicist See more In kinematic dynamo theory the velocity field is prescribed, instead of being a dynamic variable: The model makes no provision for the flow distorting in response to the magnetic … See more The kinematic approximation becomes invalid when the magnetic field becomes strong enough to affect the fluid motions. In that case the velocity field becomes affected by the Lorentz force, and so the induction equation is no longer linear in the magnetic field. … See more • Antidynamo theorem • Rotating magnetic field • Secular variation See more
