🧲 Magnetic Field Fundamentals

B-field (Magnetic Flux Density): Force per unit current per unit length

H-field (Magnetic Field Strength): B-field divided by permeability

Relationship: B = μ₀μᵣH (μ₀ = 4π × 10⁻⁷ H/m)

Force on moving charge: F = q(v × B)

Force on current: F = I(L × B)

🔬 Applications by Field Strength

• fT-pT: Quantum sensors, SQUID devices
• nT-μT: Geomagnetic surveys, navigation
• μT-mT: Biomagnetism, metal detection
• mT-T: Industrial magnets, motors
• T-10T: MRI, research magnets
• >10T: High-field research, fusion

⚡ Electromagnetic Induction

Faraday's Law: EMF = -dΦ/dt (Φ = magnetic flux)

Magnetic Flux: Φ = B⋅A = BA cos(θ)

Lenz's Law: Induced current opposes flux change

Motional EMF: EMF = BLv (conductor moving in field)

🌍 Earth's Magnetic Field

Total Field: ~25-65 μT (varies by location)

Horizontal Component: ~20-30 μT at mid-latitudes

Vertical Component: 0 at equator, ±60 μT at poles

Declination: Angle between magnetic and true north

Inclination: Dip angle from horizontal
