A girl is trying to make a simple electromagnet to help her pick up a piece of metal she dropped under a car. Which list of materials would she need to make an electromagnet?

Answer 1

To make a simple electromagnet, the girl would need the following materials:

1. Iron nail or screw: This will be used as the core of the electromagnet.
2. Copper wire: A long, insulated copper wire will act as the coil around the nail/screw.
3. Battery: Any size of battery (AA, AAA, etc.) with enough voltage to power the electromagnet.
4. Alligator clips or insulated wire: These are used to connect the battery to the copper wire coil.
5. Piece of metal: The girl needs a small piece of metal to attract/pick up using the electromagnet (e.g., a paperclip).

It's important to note that safety measures should be considered when working with electricity, such as using proper insulation, and adult supervision is recommended for younger individuals.
