Metallic rod on an isolated support, at the upper end of which there are narrow paper strips, which outlines the electric field lines by approaching an electrified wand near the rod.
Rod height : 200 mm
Paper strips : 100mm
20 strips

Magnetic needle, with longitudinal dimension of 100mm.
With support for the center axis, with conical bearing with needle.
With N and S poles painted in blue and red respectively.

Two coils with 200 turns made of enameled copper wire each
The power supply 4-6 V DC source
The coils may freely place the lateral arms of the core
The distance between the axes of the core arms 5 cm.

The model have six diametrically and equally spaced transparent plates, one of which is interchangeable
On the plates a lot of easily moving ferromagnetic arrows
One of the interchangeable plates has an arcuate notch for installation in a U-shaped magnet model

Magnetic needle, with the longitudinal dimension 40 mm, with support for the median axis and conical bearing with needle
With N and S poles colored in blue and red, embedded in a cylindrical transparent plastic box with a diameter of 45mm.
The needle pivot on the axis so that it does not fall by twisting the box
