Includes 1 magnet wand (7.63 inches long) in assorted solid colors and 5 bicolor magnet marbles (.63 inches in diameter). Ceramic magnets are completely encased in plastic. Ceramic magnets are the most lightweight and economical magnets. Children safety tested for ages 4+.
An efficient and easy way to demonstrate Faraday's Law and Lenz's Law. To show and teach how a magnet when passed thru the complete loop causes the loop to move and when passed thru the cut loop causes no movement. 6"H x 7"W. 2.25" Diameter loops.
Made of chrome steel with marked poles. Dimensions: 6" x 3/4" x 1/4". Set of 2. Includes plastic box.
Odd-shaped magnets make odd-shaped magnetic fields. This kit has seven very powerful neodymium rare earth magnets in seven unusual shapes. When placed near or on top of the included magnetic field viewer containing iron filings, the iron filings line up in amusing patterns. The 2.5" x 3.5" viewer is sealed so the filings won't spill or stick. Shapes included: bar, star, heart, disk, triangle, ball and ring. With 3/4" x 4" keeper and instructions.
This educational kit contains materials and instructions suitable for safe hands-on inquiry-based experimentation into the nature and properties of magnets and electromagnetism. This kit is primarily aimed at students in Middle School but may be used by Elementary or High School students by slightly altering the instructions. Instructions are also included for Science Fair activities and optional Probeware/Data-Logging activities. Experiments that can be performed include how a compass works, why and how magnets react to things, is electricity magnetic, working of an electromagnet, can magnets generate electricity, analyzing a generator, construction of a motor etc.
Kit includes: Dynamo Generator AC/DC-1, Motor model-1, Bar Magnet-2prs, Horseshoe Magnet-1, Aluminum Strip-1, Iron Strip-1, Copper Strip-1, Zinc Strip-1, Electromagnet-1, Contact Key-1, Magnetic Compass-2 & Oersteds Law Apparatus-1.

To study Spectral Lines of Pure Elements / Gases. Gas under pressure in the tubes is used to produce a light for spectral analysis. Brightness of light depends on the nature of gas. Optimum intensity, line resolution and longer life. Metal ends with long life electrodes. About 26 cm long, with 90 -100 mm of central capillary. For intermittent use only, not to be used as a lamp source. These are designed to operate 30 seconds ON~30 seconds OFF. Need Spectrum Tube Power Supply or an Induction Coil, sold separately.
