An electromagnet and method for producing an electromagnet. The electromagnet includes a sheet metal casing encompassing a magnetic coil at its end face on a magnetic pole side and extends into an interior of the magnetic coil and forms, in this case, a magnetic pole which interacts with a magnet keeper. The electromagnet enables actuation of a valve, a coupling or a reciprocating pump. The structure is achieved with as few cutting processes as possible to be used for generating the individual parts and as small a number as possible of individual parts is to be used per electromagnet.

Apparatus for aligning magnetic wire aligns magnetic wires on a wire alignment substrate along its base lines, which are positions the magnetic wires are aligned with, with a small interval and without inducing torsional stresses. A microscope is used to detect misplacement between the base line and a reference line that is the magnetic wire taking a form of a straight line under application of tensile force and pulled out by a wire chuck. The misplacement is corrected using a position adjustment device of a substrate attaching base to which the wire alignment substrate is attached. The magnetic wires are temporarily fixed to the wire alignment substrate by magnetic power, and then permanently fixed to the wire alignment substrate using resin while free from the torsional stresses.
