Introduction

The EM-8662 Ring Launcher Accessory includes three non-mag­netic metal rings, and an induction coil attached to a light bulb.
These accessories are designed to be used with the EM-8661
Ring Launcher for demonstrating electromagnetic induction and
magnetic force. The rings slide over the iron rod of the Ring
Launcher, and, when the launch switch on the Ring Launcher is
pushed down, the rings “jump” to different heights. The split alu­minum ring is used to demonstrate what happens if there is not a
complete conductive path. When the coil of the induction coil
and bulb is placed around the iron rod, the bulb lights while the
launch switch on the Ring Launcher is held down momentarily.

Setup

• Follow the instructions and safety reminders described in the
EM-8661 Ring Launcher Instruction Sheet.

WARNING: Do not immerse the rings or the induction coil and
bulb into water before using the Ring Launcher. Also, do not use
the rings or the induction coil and bulb around water or with wet
hands.

CAUTION: To prevent the rings from hitting other objects or
people, allow a one meter radius of space around the Ring
Launcher and a two meter distance above the Ring Launcher.

WARNING: Do not place your face or any part of you body
directly over the top of the iron rod or anywhere in the launch
path.

Using the Induction Coil and Bulb

When used with the EM-8661 Ring Launcher, the Induction Coil
and Bulb allows you to show how voltage induced from the cop­per coil on the launcher can light the bulb.

Hold the plastic base of the induction bulb over the iron rod so
that the copper coil on the plastic base is near the copper coil on
the Ring Launcher. While holding the induction bulb near the
copper coil, use the other hand to briefly hold down the Launch
Switch.

• The small light bulb will light up..
