Development and application of measurement techniques for evaluating localised magnetic properties in electrical steel

<p>This paper reports the development of a measurement probe which couples local flux density measurements obtained using the needle probe method with the local magnetising field attained via a Hall effect sensor. This determines the variation in magnetic properties including power loss and permeability at increasing distances from the punched edge of 2.4% and 3.2% Si non-oriented electrical steel sample. Improvements in the characterisation of the magnetic properties of electrical steels would aid in optimising the efficiency in the design of electric machines.</p><p>Research results based upon these data are published at https://doi.org/10.1016/j.jmmm.2017.11.036<br></p><p><br></p>
