Magnetising a needle with static electricity using silk cloth
Nov 13, 2021 · A nautical navigation textbook on my table says that we can magnetise a non-magnetised needle by rubbing it with a silk cloth. I decided to cross check on the internet, and found …
How can permeability $μ$ of a ferromagnetic material decrease with ...
Feb 14, 2025 · Permeability is closely related to susceptibility. The susceptibility tells you how magnetization of a material changes when you apply a magnetic field. For weak fields and …
Does the magnetic susceptibility of paramagnetic materials decrease …
Dec 31, 2024 · When a paramagnetic material is placed in a magnetizing field (H), it gets magnetized due to the alignment of magnetic dipoles within it. For a certain temperature (kept fixed), is it possible …
Where does the energy for magnetizing a metal come from?
I saw a young man's science project. He asked this question in a different way "does magnetizing something reduce the magnetic field potential of the original magnet?" His answer experimentally w...
Magnetic susceptibility for ferromagnetic materials
May 26, 2022 · Notice that high intensity fields are, in principle, capable of magnetizing the material in a single direction -- making it isotropic, but not necessarily homogeneous. In case you are not familiar …
