Investigate magnetic fields produced by an electric current. Students observe as a current carrying coiled wire produces a magnetic field perpendicular to the direction of the current. Students learn that the strength of the magnetic field varies with the number of times the wire is coiled and voltage applied across the coils. Complete instructions provided.

Students can discover how people communicated long distances before the telephone. With the Telegraph Kit, students can learn Morse code and even send a secret message to a friend. Kit includes: D cell battery holder, contact key, light bulbs, alligator connector cords, buzzer and instruction manual .
