Cat: EM1820-001
(‘U’ core & armature)
This simple electromagnet consists of two 10mm diameter iron cores inserted into bobbins
and wound with copper wire. Each iron core is welded to a yoke so that a ‘U’ shaped
magnet is formed. Each side of the bobbins, 4mm socket head spin free terminals permit the
connection of either wires or 4mm banana plugs. The two bobbin coils are connected in
series with one another so that the current in one coil is the reverse direction to the other so
that when DC current flows through the coils, one pole becomes a NORTH pole and the other
becomes a SOUTH pole.
A flat iron ‘Armature’ is provided to close the magnetic circuit. The armature is held tightly
to the poles by the magnetic field. The armature is provided with a hook so that weights
may be hung to determine the holding force of the electromagnet.
Physical size: 10mm diam cores,
Approx. 100x100mm overall Weight: 0.31 kg
