Where is the Magnet?
A magnet often seems to be doing all the attracting when brought near a magnetic (iron containing) item such as a paperclip or refrigerator. This simple demonstration shows the attraction is mutual between a permanent magnet and a magnetic item.

Idea Sheets are cross-referenced to subjects listed in the Common Core, Next Generation Science Standards, and California Content Standards.
Ask questions to determine cause and effect relationships of electric or magnetic interactions between two objects not in contact with each other. [Examples: the electrical forces between a charged rod and pieces of paper; the force between 2 permanent magnets, the force between an electromagnet & steel paperclips, Focus on forces produced by objects that can be manipulated by students, & electrical interactions – limited to static.] “||Next Generation Science Standards||Grade 3||Physical Science||Motion and Stability: Forces and Interactions |||Define a simple design problem that can be solved by applying scientific ideas about magnets.
