The principle of measuring instruments - two rollers in the
This experiment demostrates ferromagnetic measuring principle přístrojes two mA ferromagnetic coil rolls in the cavity.
Educational phase: motivation
- connecting wires
- two ferromagnetic cylinders
The coil is connected to the source induces a magnetic field. Consistently sticks and magnets will repel each other. The more current flowing the coil, the more they repel.
Application in practice
Ferromagnetic measuring instruments.
