Hello. I am brand new here, and pretty new to electronics in general. I am working my way through some textbooks and reading a lot online.
Here is my question. I found an "experiment" online about winding magnet wire around a straw to make a magnetic field and passing a metal rod through it. What I want to know is, is the electromagnet then a load, with some resistance? If I just attach the ends of the coiled wire to each end of a battery will the current be practically uncontrolled and burn up the battery?
Thanks in advance, and I look forward to learning a lot here. I will be looking through all of those links in the FAQ as well. Looks like good stuff there.
