transformers and motors we are using at home are made of
electromagnet.
D.Discussing new concepts and The force exerted by a magnet when it attracts or repel things is called
practicing new skills #2 magnetism. Magnetism is caused by the motion of electric charges. The
stronger the electromagnet is, the stronger the magnetism it produced. How
are we going to make an electromagnet stronger? There are many factors
that affect the strength of an electromagnet. One of these is the number of
dry cells used. If you use more dry cells, it means more electrons flowing in
NUMBER OF LOOPS An electromagnet is made the electromagnet, and therefore, it can produce stronger magnetism.
out of a coil of wire wrapped around a metal core
-- usually iron -- and connected to a battery. As the
electrical current moves around the loops of the
coil, it generates a magnetic field like that of a
small bar magnet. It has a north pole on one side
of the loop and a south pole on the other. Because
the coil is made out of one continuous wire, the
magnetic fields of each loop “stack up,” creating
something like a large bar magnet. One way to
increase or decrease the strength of the magnetic
field is to change the number of loops in the coil.
The more loops you add, the stronger the field will
become. The more loops you remove, the weaker
the field will become.
THE METAL CORE The metal inside the coil
magnifies the field created by it. Changing the
metal core for a different metal will make the
electromagnet stronger or weaker. Iron cores
make for very strong fields. Steel cores make
weaker fields. Neodymium cores make the
strongest fields. Sliding the core partially out of the
coil will weaken the field, because less of the
metal is within it.
BATTERY CURRENT Changing the amount of
current flowing through the electromagnet will also
change the field it produces. The greater the
 current in the coil, the stronger the magnetic field
will grow. Conversely, lowering the battery voltage
decreases the current, weakening the field. This
fact has a complication, however: when you
increase the current, the magnet wires get hotter,
and possibly fry the delicate electrical insulation
without which the magnet can't work.
WIRE SIZE Although metal wires are very efficient
conductors of electricity, they still have some
resistance to the flow of current. Using larger
gauges of wire on the coil will decrease this innate
resistance. This will increase the current and
therefore the field. Using smaller gauges will
increase the resistance, reduce the current and
weaken the field. Using different types of metal
wire will also affect the field strength, because
every metal has a different inherent resistance to
current.
