armature reaction means when load is added to the armature then current is passed through armature conductors then in armature creates flux. It is demagnetize and cross magnetize the main field flux. in other ward it is effect of armature field on main field.

Switching of the poles?
This question doesn't really have enough information. I'll assume that you are talking about a DC circuit where switching of the poles would mean to reverse the polarity of the circuit, ie switching of the poles would mean to switch the positive and negative leads of the circuit. This term is also associated with motors. Switching of the poles in motors is what causes the rotation of the armature. The brushes of the motor induce a current into the armature, as the armature rotates the brushes come in contact with other bars on the armature thus "switching of the poles".
What do mean by extent of reaction?
Extent of the reaction measures how far a reaction will proceed before establishing equilibrium state .
What word means to be new to something?
Armature
What does biochemical reaction mean?
it refers to a chemical reaction that normally will be performed within a living oranism
When a current flows through an electric bell what will happen to the armature?
When current passes through an electric bell, the armature gets magnetised and attracts the gong hence ringing the bell.
What are the effect of armature reaction in DC machine and how the armature reaction is minimise?
Armature reaction is the interaction between the magnetic flux produced by armature current and that of the main magnetic field in an electric motor or generator.
What is mean by armature reaction reactance?
The related link below shows you in detail.
What is the difference between armature reaction and armature reactance?
armature reactant means loss in armature associated with inductive properties of the coil, while armature reaction include losses due to magnetizing component of current flowing through armature.
Why the induction motor does not have armature reaction?
Because the armature (or rotor) has no external connection. The currents that produce torque from the rotor are induced by the magnetic field in the machine, so there is no commutator, no brushes and no armature reaction.
Why pole face are chamfered in dc machine?
in order to reduce armature reaction.
What are compensating winding?
compensating windings are used to overcome armature reaction
What is armature reaction in dc machines?
The armature reaction is the interaction between armature flux and field flux when current is introduced to a dc motor. It results in a cross-magnetizing effect and a demagnetizing effect.
What is armature reactions in a synchronous machine?
Armature reaction is the effect of armature flux on the flux generated by the fied windings.Cross magnetisation and Demagnetising are its consequences.
Armature reaction in a DC generator?
ARMATURE REACTION in DC MachineAll current-carrying conductors produce magnetic fields. The magnetic field produced by current in the armature of a dc generator affects the flux pattern and distorts the main field. This distortion causes a shift in the neutral plane, which affects commutation. This change in the neutral plane and the reaction of the magnetic field is called armature reaction.
How you can reduce the effect of armature reaction?
by using capacitor
What is armature reaction in dc motor?
Armature reaction is effect of armature flux on main field flux. Basically there are two windings in a dc motor - Armature winding (on stator) and field winding (on rotor). When we excite the field winding, it produces a flux which links with the armature. This causes an emf and hence a current in the armature. This current in armature produces another flux which lags the main flux. This is referred to as armature reaction. It has two effects on the machine: 1. Demagnetising effect: It reduces the strength of the main flux. 2. Crossmagnetising effect: Its effect is that it bends/distortes the the main flux line along the conductor
How do you reduce armature reaction?
By Using Interpoles (Auxillary Poles).......
