1. Introduction

One of the many important technical fields is materials science. It is not surprising that this science is among the fastest-developing domains because choosing the right material for manufacturing a product is crucial for this product to work properly for a long time. Apart from prolonging the service life of products, appropriately selected materials also increase the safety of such products, while reducing the demands on natural resources. Normally, finished products are tested for bugs in order to prevent complaints or even accidents. However, as some materials are quite rare and therefore expensive, NTD methods come on stage. “NDT” stands for “non-destructive test methods” and, as this technical term suggests, these methods test a material without destroying the product being tested. Unit 10c is going to deal with these methods.

Although magnetic particle testing is an inexpensive method, it is not applied widely because its use is limited to ferromagnetic materials.

OK, let´s get started. Does everyone have a copy of the agenda?
