A hands-on introduction to electrical basics
What is parallel circuit or a series circuit? How does a fuse work? What is a short circuit? Simplify and understand circuit diagrams. Experiment with the theory of electricity utilizing the unique "breadboard".
Solenoid Valves are used for investigating magnetic fields and the force between conductors.
Choose this large diameter air core solenoid to investigate 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 enameled #16 niclad copper magnet wire, allowing it to carry 5 a continuously, or 10 a intermittently.
Demonstrate the Force Developed by an Electromagnet 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.
