Mercury Magnetic
MAGNETOSPHERE
Global Shield
Mercury's magnetic field creates a protective bubble that deflects high-energy particles from the Sun.
Weak but highly active.
Symmetric magnetic poles.
Plasma Shield
The Magnetosphere. A dynamic boundary where Planetary Magnetism meets the violent energy of the Solar Wind.
- 🧲 Global Field: Generated by the churning molten iron core.
- 🌬️ Solar Deflection: Redirecting charged particles around the planet.
- 🌪️ Tornadoes: Magnetic events that funnel plasma to the surface.
Shield Oat
Magnetic Strength. A thin but vital barrier that redirects Solar Plasma around the planet's metallic core.
- 🧲 300 nT: The average magnetic intensity at the equator.
- 📏 Asymmetric: Stronger in the North, vulnerable in the South.
- 🌪️ Compression: Solar wind can push the shield into the surface.
Storm Impact
Shield Compression. During solar storms, Mercury's Magnetic Barrier can be pushed directly into its surface.
- 🌪️ Tornadoes: Magnetic funnels carry plasma to the ground.
- ☄️ Sodium Tail: Atoms stripped from the crust form a comet-like tail.
- ⚠️ Exposure: The shield can fail completely during extreme flares.
Shield Breach
Compression Event. When solar pressure exceeds magnetic force, the Magnetopause collapses toward the surface.
- 📉 1.5 → 1.0 Rp: The shield can shrink by 30% or more during storms.
- 🚫 Exposed: Solar plasma makes direct contact with the crust.
- 🧪 Sputtering: Atoms are blasted off the surface into the exosphere.
