Weekly Blog 03/20 - Build the Best Electromagnet

To build the best electromagnet we need to have a wire,battery and some Iron fillings.And we need the battery to be connected to the wire and the iron fillings to be the thing that gets picked up by the magnetic circuit.It will work because the wire is connected to the battery and the battery now has the power to pick up the iron fillings but if the wire is not held where it supposed  to be held it might not work.
