Question 4
The operating principle of an electric motor is based on the permanent magnet, capable of
attracting objects such as steel and iron, when they interact with its magnetic field (magnetic
force of the magnet). Choose the alternative that represents a false claim:
a. None of the alternatives
b. The Magnetic Field is represented by magnetic flux lines that circulate from the north
pole towards the magnet's magnetic south pole. The larger the number of lines, the more
intense the field in this region.
c. The force of the magnetic field is proportional to the current intensity in the conductor.
d. When a conductor is coiled in coil form, the flow lines produced by the turns form a
constant magnetic field, similar to an electromagnet. When a conductor is coiled in coil form,
the flow lines produced by the turns form a constant magnetic field, similar to an electromagnet.
Questão 5
Losses are considered in the core:
a. which include friction in the motor and cooling fan bearings.
b. None of the alternatives
c. represents the energy needed to magnetize the core material (hysteresis) and the losses
due to the creation of small foucault currents.
d. represent the loss of heating due to the current flow (1) through the resistance (R) of the
stator and rotor windings.
