So I have a science experiment I have to do. I‘m doing magnet strength. I have a magnet, and it doesn‘t pick up any of the paperclips through the wood, or the Mild Steel. I need explanations but I can only say that it doesn‘t go through the wood because wood is an insulator so it can‘t pass through. What about the Mild Steel? I can‘t explain that one and I really need an explanation. The mild steel is less than a centimeter thick (what‘s it. a decimeter?) and its 5x(a little less than 6)All help is much appreciated, spam is not appreciated, if it‘s not the right answer dont‘ bother posting please.
If it can't pick up small things through wood, it's too weak a magnet for the thickness of wood used. Change one or the other. The fact that a material is an insulator or a conductor has no effect on the static pull of a magnet. Magnets can pick things up through a sheet of copper or wood. Pure soft iron will pass magnetism through a decent distance but many steels will not. Soft iron is highly permeable, which means it can strengthen the magnetism of a source such as an electromagnet coil. On the other hand, soft iron doesn't retain much magnetization after the magnet is removed, while steel can be magnetized semipermanently at least (typically by stroking it in one direction, if it's elongated like a nail). See the ref. EDIT: OK it picked up things through stainless steel, which, BTW, is an electrical conductor. What I mean by soft iron will pass magnetism (vague term) is that the material acts like an extension of the magnet. So you should be able to pick things up through a thicker piece of soft iron (or apparently stainless), than of wood.
You can spray degreaser on it and wash it off it will be fine I wash my engine every time I wash my car
