س/لماذا زودت السفن الحربية للحلفاء في الحرب العالمية الثانية بأجهزة لإزالة المغنطة؟

ج/ تشكل الكتلة الحديدية لبدن السفن الحربية وأجزائها مجالاً مغناطيسياً .وقد استفاد الألمان من هذه الظاهرة وبدأوا منذ عام 1939م في استخدام طوربيدات "نسائف" بحرية مضادة للسفن تنجذب في اتجاه المجال المغناطيسي للسفن . وقد طور الانجليز أسلوباً مضاداً يمكن به إزالة المغنطة ، وذلك بلف أسلاك تحمل تياراً كهربائياً ضعيفاً حول بدن السفينة ، وفيما بعد أصبحت أسلاك إزالة المغنطة من الأجهزة القياسية الثابتة في السفن الحربية . وتصنع الآن أبدان سفن كسح الألغام من مواد غير معدنية
