The bar magnet as a dipole, the Earth as a magnet, and matter's response to fields.
Zoom out from moving charges to whole magnets and materials. Treat a bar magnet as a magnetic dipole and let it swing in a field to weigh its moment, trace the hysteresis loop of an iron core and read its retentivity and coercivity, measure the Earth's angle of dip, and sort diamagnetic, paramagnetic and ferromagnetic samples by how a field pushes or pulls them — the CBSE Class 12 'Magnetism and Matter' chapter, made tangible.
Beyond the open showcase, subscribed schools get the growing library of Magnetism & Matter experiments — searchable, tagged by concept and difficulty, and expanding continuously.
