Mrkněte na pěkné a názorné vysvětlení MAGNETICKÝCH interakcí mezi kusancem hliníku (který je paramagnetický), železa (feromagnetické) a permanentního neodymového magnetu.🧲

Zmiňované "eddy currents" znáte z hodin fyziky jako "vířivé proudy" - zjednodušeně jak proniknou magnetické siločáry z magnetu do toho kusance kovu, vyvolají elektrické proudy tvaru smyček, které zase vyvolají vlastní sekundární mag. pole a taky teplo v materiálu, ale v našem případu jde hlavně o opačné mag. pole, které interaguje s původním.🤜🤛 …a to vede k zajímavému jevu magnetického brzdění pohybu magnetu nemagnetickým materiálem… …nu alébrž je to kusanec kovu s nějakým odporem, tak se vířivé proudy za chvilku utlumí a ztratí a vliv brzdění opadne.😵

ALE…a teď přijde ta vědecká magie🧙‍♀️…když matroš nemá odpor (vnitřní elektrický, ne ten lidský k učení😅), jako třeba supravodič, tak vířivé proudy nejen vydrží déle, ale prakticky neomezeně…a ejhle, máme SUPRAVODIČ a magnetickou levitaci (tzn. sekundární magnetické pole se neztratí a drží magent v přesně v pozici jejich vzniku).🤏

Takže ukázka od Dr. Jamese J. Orgila z The Action Lab ukazuje na ochlazeném kusu hliníku ten mezikrok, kdy odpor klesá a vířivé proudy vydrží déle a tedy tlumí víc…až se dostane k bezodpornému :) supravodiči, kde to drží furt. Myslím pěkné a názorné vysvětlení.👏

🧲☄️ Researchers at the University of #Colorado #Boulder suggest that powerful magnets could provide a way to redirect #asteroids without touching them.

By using a #spacecraft to generate a magnetic field, scientists could nudge metallic #space #rocks into safer orbits. The method offers a more controlled alternative to physically crashing probes into asteroids.

We could protect Earth from dangerous asteroids using a huge magnet

A new spacecraft concept called NOVA could keep asteroids from hitting our planet by using a huge magnet to gradually pull them apart while shifting their trajectories

More Rapid Depression Therapy. A treatment for clinical depression that typically lasts six weeks could be compressed into just five days with comparable results. #depression #tms #magnetism

Howard G. Smith MD, AM on Instagram: "More Rapid Depression Therapy A treatment for clinical depression that typically lasts six weeks could be compressed into just five days with comparable results. Psychiatrists at the UCLA Health Sciences report this advancement in the Journal of Affective Disorders. This development is an accelerated form of transcranial magnetic stimulation, or TMS. The study included 175 patients. Of those, 40 patients underwent the accelerated “5-by-5” protocol, receiving five sessions a day for five days. The control group of 135 received the standard treatment: one session per day, five days a week, over six weeks. Both groups showed significant reductions in depressive symptoms with no statistically significant difference in overall outcomes. Some patients in the accelerated group demonstrated a delayed effect with depression scores dropping an average of 36% but requiring two to four weeks post treatment. These findings point to a potentially faster, more practical option for those who don’t respond well to antidepressants. A five-day treatment could reduce barriers like time, travel, and work disruption. There is a caveat: this was not a randomized trial, and longer-term outcomes may still favor the traditional schedule. More research is needed before this rapid option is routinely offered to patients. https://www.sciencedirect.com/science/article/abs/pii/S0165032726001965?via=ihub https://www.sciencedaily.com/releases/2026/02/260224023103.htm #depression #tms #magnetism"

Mıknatıslar Neden ÇALIŞIR? Feynman'ın Açıklamayı Reddettiği Tek Soru

Richard Feynman'ın 1983'teki efsanevi BBC röportajından ilham alan bu videoda; fiziğin neden "neden" sorusuna değil de "nasıl" sorusuna cevap verdiğini ve neden tanıdık açıklamalar beklemenin sizi her zaman tatminsiz bırakacağını inceliyoruz.

Manyetizma Zamanın geriye akmasıdır!
