When electric motors with a higher performance are
required, they are generally constructed with electromagnets
instead of permanent magnets, as above all these can generate
stronger magnetic fields.
In a shunt motor, the armature coil and the field coil are
connected in parallel.
The experiments are so designed, that they only provide
qualitative or semi-quantitative results.
Assemble a model of an electric motor in which the permanent
magnet is replaced by an electromagnet, and use it to examine which
the characteristics of the motor are when the coil of the
stator and the rotor are connected in parallel.
