About

This quiz comprehensively covers magnetism concepts appropriate for middle school students in grades 6-8. The questions assess fundamental understanding of magnetic fields, magnetic domains, and the relationship between electricity and magnetism. Students need to understand that magnetic fields are invisible force fields that can be represented by field lines, and that all materials contain magnetic domains - tiny regions where atoms are aligned. The quiz requires students to distinguish between permanent magnets (where domains are aligned) and ordinary metals (where domains are randomly oriented), and to recognize that temporary magnetization occurs when materials are exposed to external magnetic fields. Advanced concepts include understanding electromagnets as temporary magnets created by electric current, recognizing that only ferromagnetic materials like iron can be magnetized, and grasping the fundamental connection between electricity and magnetism. Students must also apply knowledge about Earth's magnetic field and how it affects compasses, demonstrating both conceptual understanding and practical applications. Created by Edward Scullion, a Physics teacher in the US who teaches grades 6 and 8. This quiz serves as an excellent formative assessment tool following instruction on magnetism, whether students have watched the referenced BrainPOP video or received direct classroom instruction on these concepts. Teachers can use this quiz as a warm-up activity to activate prior knowledge, as guided practice during lesson sequences, or as homework to reinforce learning after classroom demonstrations with magnets and electromagnets. The questions effectively assess student understanding before moving on to more advanced electromagnetic concepts, making it valuable for review sessions or as preparation for summative assessments. This quiz aligns with Next Generation Science Standards MS-PS2-5, which requires students to conduct investigations and evaluate experimental designs for evidence that fields exist between objects exerting forces on each other even when the objects are not in contact.

How are the magnetic domains of a magnet different

from the domains of an ordinary piece of metal?

In a magnet, the domains all point in the same direction; in an ordinary piece of metal, they're all jumbled up.

In a magnet, the domains all point toward the north pole; in an ordinary piece of metal, they all point to the south pole.

In a magnet, the domains are very strong; in an ordinary piece of metal, they're very weak.

A magnet contains magnetic domains; an ordinary piece of metal does not
