Why Do Metallic Cylinders Rotate in a Magnetic Field?

AI Thread Summary
When a metallic cylinder is placed in a vertical magnetic field, it begins to rotate due to the interaction between the magnetic field and the electric currents induced in the metal. The rotation is a result of the Lorentz force acting on the charged particles within the cylinder, which creates a torque. This phenomenon can be explained through vector analysis, where the magnetic force and the induced current create a three-dimensional motion. The discussion highlights the relationship between magnetic fields and electric currents, emphasizing the principles of electromagnetism. Understanding these interactions is crucial for grasping the mechanics behind the rotation of metallic cylinders in magnetic fields.

When you apply a vertical magnetic field to a metallic cylinder suspended by a string it begins to rotate. Why does it do so?
Thanks

Doesn't anyone know about this?
Doesn't it have something to do with the fact that a metal rod in which electricity is flowing starts to vibrate when put under a vertical magnetic field?
I've heard something about determinants of two vectors where one is the force by the magnetic field acting vertically and the other from the magnetic field withing the metal rod. The determinant of these two go on a third axis as to make the vectors 3D, and hence it starts to vibrate. Or? Any similarities or am I on the wrong path?
