Trent builds a model electric motor. when he connects a battery to the motor, the motor spins through a half rotation and stops.
which is the most likely solution to the problem?
replacing the battery, because it is not providing current
installing new brushes, because they are not making a good connection
checking the commutator, because the current is not reversing
adding more wire coils in the armature, because the electromagnet is too weak
