I ordered two of these for a co-op class of 24 students in which we made simple and parallel circuits and an electromagnet (by wrapping wire around a large iron nail). There was plenty of wire, and the price was very reasonable.
You can never have too much wire!
We use this wire for everything including connecting batteries in series or connecting to electrodes when we run out of alligator clips (connect with clothespins), windings to make a motor, and windings to make an electromagnet.
We purchased this for physics in our homeschool. Great value for the amount of wire and this will last us through all the kids and the many science experiments in our future.
