Step by step:
1.
Join the transistor BC 547 by
7.
Connect all the elements with
the copper wire and soldering
a soldering iron and a copper
iron and fix them on a
wire with capacitor 3,3 nF,
cardboard box.
and next lead the wire to the
capacitor 2,2 nF.
2.
8.
Wind 10 coils of copper wire
onto the plastic box and
Next join the capacitor 2,2 nF
connect to one of transistors.
to the resistor 6,8 kΩ, and
connect the second transistor
BC 547 to the resistor.

resistor 220kΩ.
Connect the capacitor 220kΩ
to the capacitor 10nF which
was joined with the integrated
circuit LM 386.
5.
Connect the capacitor 10mF
to the integrated circuit. Then
connect the loudspeaker.
6.
Wind 60 scrolls of copper wire
on the glue tube and pin to the
second generator.
Connect two transistors to the
capacitor 10kΩ, join with the

9.
Join the switch with the
battery 9V.
10.
The magnetometer is ready :D!
