Easy Way to Change Resistance in a Laborator Circuit

In addition to being an excellent standard of resistance, this box is particularly good for use with AC and DC bridge, Wheatstone bridges and potentiometers. Its wide range of resistance, from 0 to 1,111,110 ohms, makes it possible to get any value bu 1-ohm steps and its accurate to within + - 0.5 &(+ - .1 ohm). The box consists of six smooth operating rotary switches in decade sequence. These are mounted on a metal panel and each value is clearly marked.

This is a simple rugged plastic bell.and is ideal for a wide range of experiments.included sturdy pressed plastic box. Pivoted armature, double coil. And nickel plated gong.

Demostrate the Force Developed by an Electrmagnet with a Single Battery

How many of your students can lift 100 times their own weight? This 6.3 cm, 0.9 Kg dissectible electromagnet can do just that-with the help of one 1.5 V D-cell battery that you provide - lifting up to 90 Kg. the core and yoke are precision - tolerated to within .03 mm. The battery is linked by alligator clips to a DC coil.

For Investigating MAgnetic Fields and the Force Between Conductors

Choose this large diameter Air Core Solenoid to invetigate the magnetic fields of a long coil or for use with the Current Balance Accessory. the interior diameter of the pheonlic coil former is slightly larger than 50mm so that it also fits over the cathode ray tube of the Mass of the Electron Apparatus. The solenoid is 15 cm long and has 570 turns of enamled #16 niclad copper magnet wire, allowing it to carry 5 A continuously, or 10 A intermittantly.
