Consider an array of 4 magnetic dipoles in a row where there are two possible orientations for the magnetic dipole at each site. The interaction between dipoles is neglected. Find the number of microstates when all the dipoles are spin-up (30 Marks)
Added by Jennifer S.
Step 1
Step 1: Since each dipole has two possible orientations (spin-up or spin-down), for a row of 4 dipoles, there are 2^4 = 16 possible microstates. Show more…

Below are different magnetic dipoles placed in a uniform magnetic field pointing upward. All the dipoles in the top row (red arrows, A-D) have the magnetic dipole moment ÎĽ and all the dipoles in the bottom row (blue arrows, E-H) have the magnetic dipole moment ÎĽ/2. Rank the dipoles according to the magnitude of the torque on them, greatest first.

Measure the dipole moment of just one neodymium magnet, or four stuck together. Is the dipole moment additive when you use two or more magnets attracted together?
