The lever arm of torque is the perpendicular distance between the pivot point of the object and the line of action of the force applied to it. It determines the effectiveness of the force in rotating an object around its pivot point. A longer lever arm results in greater torque.
Resistance to movement of magnetic lines of force is described as reluctance. Reluctance is similar to resistance in an electric circuit and is a measure of the opposition that a magnetic circuit offers to the magnetic flux. It depends on the material and the geometry of the magnetic circuit.
RELUCTANCE---lack of enthusiasm:unwillingness
The resistance of a substance to the passing of magnetic flux lines is called magnetic reluctance. It is analogous to electrical resistance in a circuit and is influenced by the material's properties and geometry. A material with high reluctance impedes the flow of magnetic flux lines, while one with low reluctance allows them to pass more easily.
The rotational equivalent of a force is a torque. Note, however, that a torque is no longer a force - it is a force multiplied by a distance.
torque of synchronous motor with out feild exitation
In a transformer, or on general, if a material is easily magnetized it has low reluctance.

Torque is nothing but a Twisting Moment.
Relatively unprovenNoisyNot-well suited for smooth torque production
torque basically is wat i mean to say.itz jst a twisting movement..
Torque ripple in a switched reluctance motor (SRM) refers to the variation in torque output during operation, which can lead to vibrations, noise, and reduced efficiency. This fluctuation arises from the discrete nature of the magnetic attraction between the rotor and stator poles, resulting in uneven torque production across different rotor positions. High torque ripple can negatively impact the performance and lifespan of the motor, making it less suitable for applications requiring smooth and precise control. Mitigating torque ripple often involves advanced control strategies and optimized design parameters.
"Reluctance" is a noun.
Reluctance.
Reluctance is the opposition offered by a magnetic circuit to the formation of magnetic flux. The symbol for reluctance is R or Rm. Reluctance is measured in amperes per weber (A/Wb). Reluctance is equivalent to resistance in an electric circuit.
Reluctant is the adjective form of reluctance.
We need to overcome this reluctance to talk openly.
