Revisits familiar electrostatics demonstrations with magnets to show that electric and magnetic forces are fundamentally different phenomena. Students see that both poles of a magnet attract a charged balloon, that …
An assortment of magnets for demonstrating attraction/repulsion, the impossibility of magnetic monopoles (broken magnets always produce two dipoles), and compass alignment with Earth's field. Useful as a hands-on introduction to …
Students see that magnetism occurs naturally in certain minerals. A lodestone (naturally magnetized magnetite, Fe₃O₄) picks up paper clips and has identifiable north and south poles, just like manufactured magnets.
Breaking a magnet always produces smaller dipoles — each piece retains both a north and south pole. This demonstrates that magnetic monopoles do not exist and that magnetic field lines …
Students observe the conversion of magnetic potential energy into kinetic energy through a cascade of collisions. A slowly rolled ball bearing triggers a chain reaction where each magnet stage adds …
Students observe that magnetic holding force depends strongly on contact area. With the smaller plate, the GE magnet holds ~1800 g; with the full-area plate, it holds ~6000 g — …
