المغناطيس الكهربائي.

09 أبريل 2014

هو عبارة عن مغنطيس يشتغل بالكهرباء.

المغنطيس يجذب الأجسام الحديدية، إذا لمست المغنطيس الكهربائي بإبرة ستصبح هذه الأخيرة مشحونة بالطاقة الكهرومغناطيسية، وتتمكن بالتالي من جذب الأجسام الحديدية.

وإذا قمت بحك الإبرة على المغنطيس الكهربائي من إتجاه الطول.

ستتحول الأبرة إلى مغنطيس وتجذب الأجسام الحديدية، حتى ولو كانت معزولة عن المغنطيس الكهربائي.
