Hi, If I have a magnetic field orientated in the x-direction, a dipole positioned on the z-axis how do I find which direction the dipole is orientated? Is it just as simple as using the right hand grip rule? In which case the dipole is orientated along the y-axis? Or is it more complicated...

Homework Statement Question 3 (a)A long metal cylinder of radius a has the z-axis as its axis of symmetry.The cylinder carries a steady current of uniform current density J = Jzez. Derive an expression for the magnetic field at distance r from the axis,where r<a. By resolving the...

need to identify the forces acting on each particle using appropriate co-ordinates system and then write the equation of motions for each of particle.

I am a bit confused by this question(see attached image). This has been posted before but I am not any further forward. My problems are: P1 - has this got the following forces acting on it: Weight, Tension, and Natural reaction force? and thus does the equation of motion end up as...
