A mag tester, wet or dry uses an electrical current to magnetize the part being inpsected. If there is a crack or flaw it shows up due to the broken magnetic field. The powder or fluid has metal particles in it. This is a surface inspection....can't really see anything inside unless it comes all the way to the surface. X-Rays are usually used for metals other than a casting, I think....I'm no metallurgist or expert. The gentleman that sponsors Top Dragster here in Div.1 could answer your question better than me.....Ernie Kendall...His company sells and services magnafluxing machines. MXI......He used to post in the Top Dragster area......maybe he would respond if you asked your question over there.....

I have to ask.....Where did you get a 4" stroke crank for a small block Mopar engine? I am not to familiar with Mopar engines but a 4" stroke is not common in a small block anything that I know of.....?
