Assembly Instructions: Experimentation Kit #2

Difficulty level: 1 (simple)

Experimentation Kit #2 allows you to compare different gauges of electromagnet wire and experiment how different wire diameters affect the performance of the motors. These experiments can be performed with all of the motors.

If you purchased this kit you need to follow the regular instructions for the motor you are assembling. However, instead of steps 10-12 for kits #1-6 or steps 11-13 for the kits #7-8, please follow the instructions below. After that you may continue the regular assembly instructions for the motor you are building.

Instructions

1. If you are assembling a reed switch motor, cut two pieces of wire 10" (25cm) long. They will be used for connecting the reed switch. Use the rest of the spool of wire to wrap around the area between the tape and the head of the nail. Try to be as accurate as possible. Tape the end and beginning of the wire using the same tape and leaving open ends of wire about 8" (20cm) long. Do not let the wire slide off the end of the electromagnet. Clean about 1" (2cm) of the wire tips with fine sandpaper (included) or a sharp knife to remove the insulation.
   
   Repeat this step for 25 (thick) and 29 (thin) gauges of wire.

2. Insert one of the electromagnets into the stand with the green star. If it does not fit tightly, you may secure it using one of the following methods. (Super Glue connection between metal and plastic is not strong enough so you should be able to take these parts apart by trying to rotate the electromagnet in the stand when you need to replace it.)

3. Place the electromagnet on the board as shown below. Turn the rotor slowly to see if the magnets hit the electromagnet. If one or more do, move the electromagnet back until there is a 1/16" (1.5mm) gap between the electromagnet and the closest magnet on the rotor. Glue the inner stand to the board. It will allow easy replacement of the electromagnets in your experiments.

If the vibration generated by the motor moves the electromagnet, wrap the inner stand with a piece of scotch tape or thin piece of paper.
