Angular velocity is a pseudovector, with its magnitude measuring the angular speed, the rate at which an object rotates or revolves, and its direction pointing perpendicular to the instantaneous plane of rotation or angular displacement.

The spin quantum number (1, 1/2, etc.) As for the transformation properties, spin, like angular momentum in general, is a pseudovector, as explained in Jess’s answer.

The magnetic field is linked to the curl of the electric field via Faraday’s law (the time derivative of the magnetic field to be exact) and since the electric field is a polar vector, it is a fairly straightforward exercise to see how the magnetic field ends up as a pseudovector.

3 Answers. Angular velocity is the cross-product of two true vectors, position and velocity, as such it behaves like a vector under rotations but does not reverse under reflections so fails to be a true vector. Neither reflections nor rotations have any effect on angular frequency, so it is a scalar.

A three dimensional vector is represented in a particular coordinate system by a triplet of real numbers. What is ordinarily meant by the term vector is called a polar vector. There is also something called an axial vector, which is the vector (cross) product of two polar vectors.

Torque is a generalized force. Like force, it causes a change in motion (but instead of momentum change, ‘angular momentum’ change). The vector cross product, by convention, obeys a right-hand-rule, so it is clear that torque, like angular momentum, is NOT energy.

In vector form, torque is the cross product of the radius vector (from axis of rotation to point of application of force) and the force vector.

Option (c) Torque is an axial vector. Axial vectors are those vectors that represent rotational effect and act along the axis of rotation. Eg: Angular velocity, torque, angular momentum etc are axial vectors.
