Our latest paper has just been published in the journal Acta Materialia. In it, we compare finite element micromagnetics simulations to experimental evidence in order to investigate the role of twin and anti-phase defects in the reduction of performance in MnAl permanent magnets. Figure: Room temperature (BH) max as a function of approximate raw material costs for the theoretical MnAl permanent magnet and experimental values for a selection of common commercial permanent magnets....

NOTE: Due to a system migration the mathematical equations within the following article are not currently functioning. I will endeavour to repair this as soon as possible Recently I have been reading through a newer edition of Young & Freedman’s University Physics, the main course textbook when I was a physics undergrad. Chapter 2 contains the following basic problem concerning 1-dimensional motion with constant acceleration. Since the book does not contain an answer or solution I decided to post a solution here....
