Simulation

Electromagnetic simulation behind our MR-safety work: the concepts each model rests on, and the analyses run with them.

Concept cards

What each modelling concept means, why it holds, and where it stops holding.

• Skin effect & skin depth
  Current crowds toward the surface; δ shrinks as 1/√f.
• AC resistance
  R_ac = 2P/I²; for a round wire R_ac/R_dc depends only on a/δ.
• Proximity effect
  Loss induced by neighbouring conductors’ field.
• Bessel function
  Origin of current crowding in round wires.
• Mutual inductance sign
  Coupling changes sign under lateral misalignment.
• Maxwell solver types
  Eight solvers by field formulation and time treatment.

Analyses

One page per simulation project: question, cases, key figures, conclusion.
