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.
Enclosed to prevent air currents from affecting the deflection of leaves. Each leaf is suspended from two small hooks. The leaves pivot, rather than bend, when charged. The front and rear side of the box is made of square glass to allow visibility. supplied with a booklet of 6 leaves.
A pair of light weight balls are suspended from a rod with a piece of string. The support rod is mounted on an insulated base. Provides a simple yet effective way to learn about electrostatics.
Flask type, conical flask with rubber stopper which holds a metal rod with disc top and lower flat end to which a leaf may be pasted. Supplied with a booklet of 6 leaves and instructions for fitting.
Materials for demonstrating the generation of electrostatic charges with friction rod . a hollow glass rods Kit includes solid glass rod and a wool friction hard rubber rod, silk friction pad, pad, flannel friction pad, animal fur( synthetic) friction pad, 3 balloons, 10 ft of string and instructions. Grades 9+
Demonstrates conversion of kinetic energy into heat and sound energy during a collision. Consists of a pair of heavy steel balls. When the balls strike against each other with a piece of paper between the balls, the heat causes a hole to appear in the paper. The kinetic energy of the balls upon collision is converted to heat which is…
To demonstrate the inverse relationship between density and length. The specimens, Aluminum, Copper, Nylon, Polyvinylchloride and Polyethylene, are all 12 mm in diameter with 15 gm mass. Length range from 15 to 100 mm. Instructions are included.
To demonstrate the conversion of mechanical energy into electrical energy. A copper disc with a turning handle rotates between two poles of a horseshoe magnet. On base with two terminals, one of which is connected to a pillar supporting the disc and the other to a brush bearing on edge of the disc.
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+.
