(0842) |
| Specifications : Base dimensions approx. 150 x 200 mm. Completely exposed demonstration model. An armature comprising two coils of copper wire is mounted to rotate about a horizontal axis. The spin of the armature is obtained for means of one hand cranked driving wheel, diameter 140 mm, coupled via a belt. Transmission ratio 1:4. The magnetic field is generated by means of one permanent U-magnet supplied with the unit. Mounted on plastic base, dimensions 150x200 mm, with two 4 mm sockets for connection to measuring instruments and a LED. Complete with 5 spare. LAWS & PRINCIPLES INVESTIGATED : • Motor spinning • Dynamo • Current generation
• Interaction between currents and magnetic fields. |
