The principle of measuring instruments - immersive magnet co
This experiment demostrates principle ferromagnetic meter vtahujícího odpuzijícho or permanent magnet.
Educational phase: motivation
- load cell
- connecting wires
- battery switch.
The principle of these devices is based on the power effect of ferromagnetic core plates located in a magnetic field coil. The hollow cylindrical coil vtahovánmagnet on the spring which caused the power steering. This principle is strongly reminiscent of the electromagnet, so these devices sometimes referred to as electromagnetic. Depending on the magnet current may have pulled or expelled from the reel.
