icon

This experiment demonstrates a magnetic field with the current thread.

Educational phase: motivation

 

Required aids+

  • model coil
  • battery
  • metal filings
  • connecting wires
  • switch

 

Experiment instructions+

E116_S001 Model will engage the thread through the switch to the battery.
E116_S002 Switch closes and we begin to model strewing metal filings. Begin to discover the magnetic induction lines.
E116_S003 After sprinkling the entire model can be observed magnetic field.
 

Explanation+

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.
