Lesson
1
What I Need to Know
 Construct an electromagnet
 Infer that electricity can produce magnetism
 Identify the parts of an electromagnet
What’s In
If you ever spill pins on a rug, you will find that a magnet is good to have. A
magnet can pick up objects with iron in them, such as steel pins.
But normally you don’t have magnets at home. So, you can instead make use
of an electromagnet. It is just a temporary magnet.
What’s New
Activity 1: Constructing an Electromagnet
What you need:
 1 pc. 1.5 v battery
 1 m long electric wire
 #4 common nail
 pins and other metallic objects
What to do:
1. Wind (coil) the electric wire 12-15 times around the nail. Remove one
centimeter of insulation from both ends of the wire.
2. Attach one end of the wire to the positive terminal of the battery and the other
end to the negative terminal to complete the circuit.
3. Bring the nail near the pins and other metallic objects. Observe how the
materials behave.
4. Predict what would happen if the wire was detached from the dry cells.
Constructing an
Electromagnet

11. 2
What Is It
Answer the following questions.
1. What are needed in making an electromagnet?
2. What happened when you put the nail over the pins and other metallic
materials? Why?
3. When one end of the wire was disconnected from the battery, what happened?
Why?
4. What is an electromagnet?
5. What are the parts of an electromagnet?
Key to answers on page 14
Did you get the correct answers? Find out.
A simple electromagnet can be made using a dry cell, copper wire coiled around
a metal rod such as a nail.
The electricity that passes through the coiled wire around the nail produces a
magnetic field that causes the nail to act like a magnet. But unlike an ordinary magnet,
an electromagnet can be turned off and on.
An electromagnet operates only when there is a flow of electricity in the coil of
wire. When electricity stops flowing through the coil of wire, the nail stops attracting
any metal on magnetic material.

The strength of an electromagnet depends on (1) the number of turns in the
coil, (2) the size of the core and (3) the number of batteries. The greater the
number of turns the coil has, the stronger the electromagnet is. The bigger the size of
the core/nail, the stronger the electromagnet is. The more batteries, the stronger the
electromagnet is.

Did you get the right answers? Find out.
The strength of an electromagnet depends on the electricity that passes
through it, the size of the metal rod, and the number of coils in the wire. A bigger metal
rod and a greater number of coils increase the magnetic field that is being produced.
Once magnetic field is produced, the metal rod has the capacity to attract other metallic
materials.

Electromagnet can be used in different ways. Most electrical devices at
home make use of electromagnets. Communication devices such as telephone,
mobile phone, radio and television have electromagnets that transmit and
produce sound.
Other electrical devices like electric toys, loudspeakers, magnetic
recording devices such as tape recorders use electromagnets. Visual devices
such as monitors also use electromagnets.
