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.

Item Code:HL-8902

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.
