SN NS SN NS SN NS NS SN NS SN NS SN Unmagnetized Nail SN SN SN NS NS NS SN SN SN NS NS NS Magnetized Nail Which of the following phenomena can this model explain, if any? Explain your answer. 1. An unmagnetized nail has no magnetic Poles at its ends. 2. A magnetized nail has both a North Pole and a South Pole at its ends. 3. When a magnetized nail is cut exactly in half, each half-piece has both a North Pole and a South Pole. 4. Both A and C. 5. It cannot explain any of the above
