InstructionsWrap several turns of the magnet

wire around the steel shaft from

top to bottom When the end of the

shaft is reached continue winding in

the same rotational direction but back

up to the top Always continue winding

in the same direction When the top is

reached again continue back down

Continue to do this until the wire

wrapping is of sufficient length As

more copper wire is used the resistance

will increase and thus require an increased voltage to run

Use Ohms law to determine the coils necessary power requirements The current

drawn by the coil is equal to the supply voltage divided by the coil resistance Power

usage is calculated as volts multiplied by amperes The higher the gauge (smaller

diameter) used for the wrapping wire the higher the resistance through the coil will be

Increasing the resistance by either increasing the wires length or decreasing its

diameter for example necessitates a higher voltage to draw an equal amount of

current and thus to maintain the same power

How to Make a Lifting Electromagnet

Electricity and magnetism are closely related and are in

fact actually two aspects of the same phenomenon

Although much is still unknown about the nature of these

forces the basic concept is that an electric current produces

a magnetic field This field can be controlled through

various means to produce electromagnets with specific

operational power ranges and lifting strength By wrapping

several turns of copper wire around a magnetic material

such as iron and controlling the electrical power through

the conductor a magnet of any strength can theoretically

be produced with sufficient ingenuity

Secure the wire wrapping with tape or tie the end of the copper wire into a knot so it

cannot unwind

Remove about an inch of enamel or insulation from each end of the wrapped wire This

electrically exposes the conductor and the wires serve as the terminals for the

electromagnet

Attach the two ends or terminals of the electromagnet to a variable voltage or variable

current power supply either directly or using alligator clip jumper wires

Turn on the power supply and adjust voltage until the electromagnet is of desired

strength

Tips amp Warnings

Magnetic field strength is inversely proportional to the square of the distance between the two

objects If a paper clip can be lifted an inch away by a certain electromagnet it would take another

electromagnet nine times stronger to lift the same paper clip at a distance of three inches (3 2)

Keep in mind magnetic fields are not properly explained by classical physics Quantum physics

and therefore advanced mathematics are needed to provide better prediction of what will happen

under certain conditions

For the engineer of lifting electromagnets however a trial and error approach can usually suffice to

produce a strong enough electromagnet

Generally a stronger current produces a stronger magnetic field If the wrapping of your copper wire

is 10 ohms and you place 30 volts across it 3 amperes will flow 30 volts multiplied by 3 amperes is

90 watts

The resistance of the copper wire wrapped around the steel shaft will create heat Expect that the

electromagnet will get hot and handle it appropriately although this will not necessarily be the case

In the worst case the enamel or insulation over the copper wire will burn and catch on fire The

copper itself may even become hot enough to melt Consider placing a fuse in line with the

electromagnet to protect the power supply in the event that this happens
