STUDY GUIDE: Big Ideas
Use to answer form questions
1.Magnetic strength decreases with distance (inverse relationship); magnets can demagnetize. Students often think magnets have unlimited strength/never wear out, but evidence from investigations shows otherwise. Use data from today's stations to identify which observations best support this understanding.
2.Energy is transformed, not consumed; charge flows in complete circuits. Students often think electricity is 'used up' in devices, but evidence from investigations shows otherwise. Use data from today's stations to identify which observations best support this understanding.
3.Electricity and magnetism are unified (electromagnetism); moving charges create magnetic fields. Students often think electricity and magnetism are completely separate phenomena, but evidence from investigations shows otherwise. Use data from today's stations to identify which observations best support this understanding.

TRUE
1. Magnetic fields only exist right next to the north and south
poles of a magnet; they do not extend into the space around the
middle.
2. Magnets will naturally attract any type of metal object,
including items made of aluminum, copper, or brass.
3. A larger magnet will always have a stronger magnetic field and
exert a stronger force than a smaller magnet.
4. Because magnetic force follows an inverse relationship, doubling
the distance between two magnets cuts their attractive force exactly
in half.
5. When two magnets repel each other, their magnetic field lines
push apart and compress in the space between them rather than
connecting.

distance and field properties explain this?
