Penelitian ini dilakukan untuk mengetahui apakah benar ada medan magnet di sekitar rel saat kereta api sedang melintas. Beberapa kecelakaan yang melibatkan kereta api dan mobil di atas perlintasan kereta api diperkirakan disebabkan karena medan megnet ini. Belum ada penelitian atau data resmi dari kepolisian yang menjelaskan penyebab tiba-tiba mesin kendaraan bermotor tersebut mati saat melintas di atas rel yang ada kereta apinya sedang berjalan. Pendapat lain juga muncul dari kejadian ini, yaitu karena sopir atau pengendara kendaraan tersebut gugup saat melihat kereta yang melintas waktu lewat di atas rel, sehingga menjadi kehilangan fokus saat mengemudi sehingga menyebabkan mesin kendaraannya mati. Data hasil pengukuran medan magnet menunjukkan bahwa nilai medan magnet di sekitar rel kereta api saat kereta api melintas rata-rata 47,73 µT, dengan nilai medan magnet terendah 22,46 µT dan nilai tertingginya 82,06 µT. Nilai tersebut tidak berbeda jauh dengan nilai medan magnet bumi yaitu antara 25-65 µT.
