The magnetic field with the current thread
This experiment demonstrates a magnetic field with the current thread.
Educational phase: motivation
- model coil
- metal filings
- connecting wires
|Model will engage the thread through the switch to the battery.|
|Switch closes and we begin to model strewing metal filings. Begin to discover the magnetic induction lines.|
|After sprinkling the entire model can be observed magnetic field.|
Magnetic field lines around the straight wire having the shape of concentric circles. When stočíme direct wire to the ring, there will be a circular thread, whose magnetic field is approximately a magnetic field around a straight wire twisted into the ring.
