3️⃣ สร้างสนามแม่เหล็กได้ยังไง

⤷ สนามแม่เหล็กแบบ Global field ไม่ได้เกิดขึ้นง่าย แต่มาจากกลไกที่เรียกว่า 'ไดนาโม' ในแกนกลาง
⤷ เงื่อนไขหลักคือ ต้องมีของเหลวที่นำไฟฟ้าได้ เช่น โลหะหลอมเหลวในแกนดาว
⤷ ต้องมีการพาความร้อน ทำให้ของเหลวร้อนและเย็นไหลเวียนเป็นวงจรอยู่ตลอด
⤷ และมีการหมุนรอบตัวเอง เพื่อช่วยจัดระเบียบการไหลเวียนนั้น

🔴 ทำไมดาวอังคาร จึงไม่มีสนามแม่เหล็ก?
🚀 DUCK Sci-fi

1️⃣ บทนำ
⤷ บทความก่อน เราคุยกันในเรื่อง ทำไมดาวเคราะห์แต่ละดวงหมุนรอบตัวเองเร็วไม่เท่ากัน
⤷ พอหันมาดู จะพบว่า โลกหมุนรอบตัวเอง 23 ชั่วโมง 56 นาที ส่วนดาวอังคาร 24 ชั่วโมง 37 นาที
⤷ แต่ทำไมโลกมีสนามแม่เหล็กคอยปกป้องดาว แต่ดาวอังคารกลับไม่มี? ⤵️

CODE RED: Solar Flares, Earthquake Warnings & Earth's Weakening Shield Is the Sun attacking our planet? A G2 Geomagnetic Storm Watch is in effect, and the Earth's magnetic shield is weaker than ever. What happens next will shock you. Welcome to the briefing room for planet Earth. Right now, multiple solar flares and coronal mass ejections (CMEs) are hitting us, putting our power grid and satellites at risk. But the danger isn't just in space. We connect the dots between this intense space weather and a disturbing uptick in major earthquakes, including recent magnitude 6.5 and 6.3 tremors. With the San Andreas and Cascadia faults long overdue for "The Big One," we have to ask: is the Sun pushing our planet's crust to the breaking point? The threats aren't just coming from our star. We'll reveal stunning new data on the bizarre interstellar object 3I/ATLAS, a visitor from another star system that is now confirmed to be outgassing anomalous clouds of nickel and cyanide. As this cosmic mystery speeds through our solar system, we turn our attention back home, to a danger growing from within: the South Atlantic Anomaly. This massive "dent" in Earth's magnetic field is expanding and weakening our only defense against cosmic radiation. This podcast connects the dots between solar storms, seismic threats, and cosmic intruders. We sift through the science to give you the critical information you need to understand the powerful forces shaping our world. Ready to look past the headlines at the real forces affecting our planet? Subscribe now, share this with anyone who needs to be prepared, and join a community that isn't afraid to ask the big questions.
