- When you connect the battery, an electric current flows through the wire coil wrapped around the nail.
- This current creates a magnetic field around the wire, which magnetizes the iron nail, turning it into a temporary electromagnet.
- The electromagnet will attract the paperclips, so when you dip the nail into them, some will stick to it.
- When you remove the battery, the electric current stops, the magnetic field collapses, and the nail loses its magnetism, causing the paperclips to fall off.
- The conclusion is that electricity can create magnetism, and this magnetism is temporary and controlled by the flow of current.
- A connection to real life is that this principle is used in many devices like doorbells, electric motors, and MRI machines.
Parent Tip: Review the logic above to help your child master the concept of electromagnets worksheet.
