This mini magnetic compass is 16 mm (5/8") in diameter. It is useful for designating the direction of magnetic fields in magnetism studies or for making simple galvanometers in electricity studies.
2 wire coils on plastic spools. Straight iron core for bar magnet, 4cm long. U-shaped iron core for horseshoe magnet, 5 cm long. Lifting bar with hook, 2 compasses, 10 steel pins, 3 insulated wires with connecting tabs, Activity guide, and storage case.
This kit allows you to see the link between electricity and magnetism. Includes a copper wire coil, a “soft” iron core, a battery holder and two paper clips. Also comes with detailed instructions to guide you through the experiments on electromagnetic fields and polarity. Requires an AA battery. Ages 7+
This compact but powerful electromagnet lifts up to 200 lb using one D-cell battery (not included). Students learn why this magnet is so powerful and what influences the strength of electromagnets. Instructions included.
Learn about magnetic fields with our Floating Magnet Set. The three ring magnets are incased in plastic and each pole is marked as N/S. They are also color coded for quick visual identification. Comes with it's own stand. 1.5 X 1.5 X 5.5”. Ages 7+
Learn all about magnetic fields with three colorful ceramic donut magnets and a pencil (included). Instructions for four simple and educational experiments using magnetic fields are included. Ages 7+.
