The power OFF state, the core of the coil has a significant magnetic

[Arthurs]

Hello everyone
When the coil is found in the middle of the two magnets,
Power the off state,
A coil having a magnetic core significantly,
When the coil out of the position detection,
Magnetic disappear, and the core is not magnetized.
Magnet width 25mm, thickness 20mm, the distance between the magnet is 75mm.
My pitch is too small magnets? Or is a normal phenomenon?
Everyone with my situation is the same?

Thank you, Yuan

I am pretty sure that state is normal for no magnetic field between the magnets

Huh? Does it run? 3 to 4 magnets spaces between is the usual.

Welding rods is terrible, and iron wire better at not retaining magnetism. Twisted wires??? Hmm. This may be easier, but is not better.
