Build an Electromagnet student sheet ... To build the electromagnet, you will need: ... Pass out the Build an Electromagnet student sheet and have students do the activity in pairs. Students will build an electromagnet and test its strength. To save time, you can pre-strip the ends of the wire for each pair of students.
