When we choice the Energy or Coenergy as the state function in determination of magnetic force and torque ?

Solutions

Expert Solution

The magnetic force and torque can be determined by choosing the state function as energy and co-energy as per our convenience.

Core energy can be defined as the energy which can be directly obtained as a function of current.

We are introduced to the magnetic field as a way to keep track of the force that arises from lenght contraction in special relativity. A moving distribution of charge becomes more dense in the right frame. So in a way, the magnetic field is just the E-field. However, when I glance over the physics of permanent magnets, it is said that their magnetic field arises from the integral sum of their electrons with aligned spin(which generates a magnetic moment).Spin is...

The potential energy of a magnetic moment in an external magnetic field is U = - ??B. U is smallest when B is parallel to ? and largest when it is antiparallel. Since the magnetic moment of the electron is directed opposite to its spin (because it has a negative charge), the electron’s energy is highest when the spin is parallel to B. The two possible energy states for the electron are the spin up state (ms = 1212) and...

When a magnet moves relative to a conducting, non-magnetic material (such as copper), some force slows down the magnet, and this is attributed to "eddy current." Describe in your own words what this "eddy current" is, how it is caused, and how this eddy current affects the magnet which caused it. In the demonstrations of eddy current, these demonstrations involve non-conservation of mechanical energy. You see: (1) large magnet slowing down to a stop at the end of a short...
