A student makes an electromagnet by wrapping a length of wire around a piece of soft iron and connects it into a circuit, as shown in Fig. 1.1. He closes the switch and finds the maximum number of paperclips that stay on one end of the soft iron.
Suggest two changes to the apparatus that increase the current.
- ______
- ______
Fig. 1.2 shows the paperclips that stay on the soft iron for three different currents. In the space below, draw a table to show the results of this experiment.
