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.
Resistivity is the intrinsic property of a conductor, and it is independent of the size of that conductor. Resistance is an extrinsic property that makes it dependent upon the amount of the material that there is present.
torque of synchronous motor with out feild exitation
In a transformer, or on general, if a material is easily magnetized it has low reluctance.

Relatively unprovenNoisyNot-well suited for smooth torque production
Torque is nothing but a Twisting Moment.
torque basically is wat i mean to say.itz jst a twisting movement..
"Reluctance" is a noun.
Reluctance.
Reluctant is the adjective form of 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.
We need to overcome this reluctance to talk openly.
