This classic Alnico Horseshoe Magnet is perfect for science fair projects or
experiments. This 2" magnet lifts up to 4 pounds. It contains
Aluminum (Al), Nickel (Ni), and Cobalt (Co) which makes for a super strong and
high quality magnet. Alnico horseshoe magnets can lift or hold about 3
times as much as bar magnets.

For studying magnetic induction properties produced by electric current and the effect of an iron core, etc.
Consists of a plastic spool with windings of enamelled copper wire having brass binding posts on square end supports. Includes a soft iron core rod of diameter 18cm and instructions.

Suitable for many experimental and demonstration needs in a general science and physics laboratory. Traditional style. Made from 5mm thick and approx. 12mm wide steel strips except for the largest size which is about 15mm wide. Painted red and stamped with N and S to indicate north and south poles. Supplied with soft iron plated keeper (armature).

The new and improved version of the Floating Wheels using Magnet Strips is very close to 100% magnet levitation! The idea is making a wheel and axle that will float above a pair of strip magnets and can rotate with no friction.

For students ages 8 and above. Adult supervision and support is required. Keep away from younger children due to small pieces.

This set includes ten, multi-colored, 3/4" diameter, ceramic disc magnets.
Ceramic magnets are made from strontium ferrite. These strong magnets can
be painted or glued to other objects making them perfect for both craft projects
and experiments.

This is a set of materials for making a very simple Electric motor to demonstrate general concepts that make motors work. This motor has only one magnet (as stator) and one simple coil (as rotor).
It can be powered by a AA battery (not included).

Iron filing, 12 ounce, in a shaker for convenience plus screw cap for safe-keeping. They are ideal for
experimentation with magnetic fields. When you place these filings on any
magnet, you can visualize 3D magnetic fields. This demonstration is very
common in the classroom and this is your chance to further study the magnetic properties at home.

Floating wheels is among the most exciting magnet levitation attempts. The idea is making a wheel and axle that will float above a set of magnets and can rotate with no friction. This is a challenging experiment and interesting novelty that provides an attractive and exciting display. This is very close to a 100% magnetic levitation constructed with static magnets.

This set comes with 6 magnets, 5 pre-cut pieces of wood and some screws. You will need a screwdriver and wood glue to complete this project. A thread or invisible string is pulling the axle from one side.

For students ages 8 and above. Adult supervision and support is required. Keep away from younger children.

Small steel balls with diameter of 1/8 inch (about 3 milimeters) are used in mechanics and magnetism experiments. As a substitute for iron filings for studying the phenomenon of magnetic fields. Form clusters and chains between unlike poles of magnets. Made of polished, hardened spheres.

Used to study electromagnetic induction & transformer principles. The outer coil is about 50 mm tall and 32 mm in diameter. The inner coil is about 58 mm tall and 19 mm in diameter. The removable steel core with handle is 10 mm in diameter and 67 mm tall. All coils are wrapped with magnet wire with insulated binding posts as connectors. (New Version. Smaller size. Includes tutorial, instructions and suggested experiments.)

For demonstrating the relationship between magnetism and magnetic effect of electric current flowing in a wire. Comprised of a permanent magnetic needle, 15 cm, free to rotate at the center of an aluminium frame suitably connected to permit current to flow over or under the needle in either direction.

For reading of topographical and tourist maps and determination of azimuthal location of a given place. suitable for overhead projection. Transparent design. Compass diameter 45mm, mounted on a 6 x 11cm transparent plastic base with scale side up to 100mm. Distance measuring scale in the front.
