Abstract (en)
[origin: DE10137519A1] An inductive sensor on a railway line detects a change in a magnetic field as the iron wheels of a railway vehicle pass over a rail. A system with first (La) and second (Li) coreless coils compensates for interfering magnetic fields (\=Fs). The first coreless coil optimizes this compensating effect along with the second coreless coil that fits inside the first coreless coil and generates a magnetic field in an opposite direction during a combined supply of current.
