Electromagnetic Induction Simulation
This simulation demonstrates electromagnetic induction in a square loop as the magnetic field decreases to zero.

Explanation:
When a magnetic field through a conducting loop changes, it induces an EMF (ε) and current (I):
- Initial flux Φ = BAcosθ = (0.10 T)(0.01 m²)(cos45°) = 0.1×10⁻²/√2 Wb
- Change in flux ΔΦ = Φ - 0 = 10⁻³/√2 Wb
- Induced EMF ε = |ΔΦ/Δt| = (10⁻³/√2)/0.7 ≈ 1.0 mV
- Induced current I = ε/R = 1.0 mV/0.5 Ω = 2.0 mA
Where θ = 45° is the angle between the magnetic field (NE direction) and the loop's normal (vertical).
