Electroplated a 5 micron layer of copper a few days ago. Was wondering why there's sulphuric acid in the solution.

Hi, I have scoured through scores of websites but haven't found a reasonable solution. The thought problem goes like this. Take any NdFeB magnet which is saturated say to B_r =1.3 T. Is there a magnetization (M) value that corresponds to the this remanence. I have been able to find a few...

Thanks!

Hi, I wanted to calculate elliptic integrals (K & E) for a given function in Mathcad. I was not able to find the appropriate function. I am using Mathcad 15. Regards, -sgsawant

Thanks! But that's a very specific case - I am necessarily looking for a general case solution. I appreciate your effort though.

Hi, I wanted to calculate the magnetic field of a cylindrical magnet at a point P (r,ɵ,z). The magnet can be at the origin or anywhere convenient. Preferably the axis of the magnet is aligned with the z axis. The magnet is of radius r_m and height h_m. The remanent flux density of the...

I am writing a paper for a journal. The paper is supposed to have quite a few circuit diagrams. What software should I use to draw the circuit diagrams?

Thanks mate! That was quite informative. The poles argument really made it clear.

Thanks for your reply. But the cases where 2 * zeta * omega is valid - for those that I have seen - have omega squared in the numerator and also as the constant in the quadratic of s in the denominator. Thus omega can be usually simply calculated (either by taking the root of the numerator or...

I have a transfer function for system. 23.23*s + 1.421 ------------------------------------- = tf s^2 + 25.88*s + 1.421 Since the numerator has a non-zero coefficient for "s" I am wary about equating 25.88 = 2 * zeta * omega [the stuff we usually do for calculating the damping...

Just a refresher. Can someone answer the above question?

I have a data of a system (2nd order spring-mass-damper). From the looks of it, the system is quite certainly overdamped. Can someone guide me as to how to find the damping ratio? Regards, -sgsawant

Great!
