10. Insert the battery and briefly connect electromagnet wires to the battery. If nothing
happens switch the wires. With the correct connection electromagnet repels the permanent
magnets and the rotor stops in the position shown below. This is a perfect test for the
electromagnet and the magnets orientation: rotate rotor quarter turn four times – if all
permanent magnets are oriented properly rotor should always stay in the position shown.
11. After you found the correct connection trim red (positive) wire from the battery holder and
corresponding electromagnet wire. Remove the insulation from the wire tips and twist them
together. You may tack this connection under the battery holder.
12. Fasten the reed switch to 1x2 brick with side holes using cable ties. Trim them with scissors.
