Magnetic Field Simulator

Models the B field of currents going through straight wires or solenoids. The init.cfg file can be modified with text-editing software to customize the initial conditions.

*** Clarification: "Scale plot step" multiplies the number of points rendered by the specified scalar, so if the UI is too laggy, decrease the value in that field.

  • For the calculations, using:
    • μ0 = 4 Math.PI E-7
    • note that in Java a 64-bit double gives ~16 significant figures of accuracy
