Question:
The pole strength qm of a bar magnet is defined by qm = |μ|/L, where L is the length of the magnet. Show that the torque exerted on a bar magnet in a uniform magnetic field B is the same as if a force +qm B is exerted on the north pole and a force –qmB is exerted on the south pole.

In Physics, a force is an influence that can change the motion of an object. A force can cause an object with mass to change its velocity, i.e., to accelerate. Force can also be described intuitively as a push or a pull. A force has both magnitude and direction, making it a vector quantity. In this video, the concept of force and torque is demonstrated with the practical application of changing the flat tire of the car.
