A strong electromagnet made of noise filter inductor & 3V battery.
This electromagnet can lift 5 kg dumbbell.
The noise filter extracted from electric rice cooker.(The cooker is using principle of induction heating)

강력한 전자석은 노이즈 필터 인덕터와 3V 건전지로 만들어졌습니다.
이 전자석은 5 kg 아령을 들어올릴 수 있습니다.
노이즈 필터 인덕터는 전기밥솥에서 추출 하였습니다. (유도가열 방식)
