Electromagnetic Induction Simulation

Electromagnetic Induction Simulation

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

Induced EMF (ε)

0 mV

0 mV 1.0 mV

Induced Current (I)

0 mA

0 mA 2.0 mA

Explanation:

When a magnetic field through a conducting loop changes, it induces an EMF (ε) and current (I):

  1. Initial flux Φ = BAcosθ = (0.10 T)(0.01 m²)(cos45°) = 0.1×10⁻²/√2 Wb
  2. Change in flux ΔΦ = Φ - 0 = 10⁻³/√2 Wb
  3. Induced EMF ε = |ΔΦ/Δt| = (10⁻³/√2)/0.7 ≈ 1.0 mV
  4. 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).
