How to Make an Electromagnet

An electromagnet is an electrical magnet and in this tutorial, i will show how you can make an electromagnet

at home, or for a science project very easy no effort with common stuff in a reusable way and with things that are

already made just waiting to be discovered.

An electromagnet is a type of magnet in which the magnetic field is produced by an electric current. The magnetic field disappears when the current is turned off. Electromagnets usually consist of insulated wire wound into a coil. A current through the wire creates a magnetic field which is concentrated in the hole in the center of the coil.

The wire turns are often wound around a magnetic core made from a ferromagnetic or ferrimagnetic material such as iron; the magnetic core concentrates the magnetic flux and makes a more powerful magnet.
The main advantage of an electromagnet over a permanent magnet is that the magnetic field can be quickly changed by controlling the amount of electric current in the winding. However, unlike a permanent magnet that needs no power, an electromagnet requires a continuous supply of current to maintain the magnetic field.

A simple electromagnet consisting of a coil of insulated wire wrapped around an iron core. A core of ferromagnetic material like iron serves to increase the magnetic field created.

For this project, we will need an electrical pump.

A pump is a device that moves fluids (liquids or gases), or sometimes slurries, by mechanical action. Pumps can be classified into three major groups according to the method they use to move the fluid: direct lift, displacement, and gravity pumps.
Pumps operate by some mechanism (typically reciprocating or rotary) and consume energy to perform mechanical work by moving the fluid.

The pump used in this project is a washing machine drain pump

First, you have to remove the black plastic that normally covers or holds in the round magnet

that spins inside generating the rotation movement for eliminating the water from your washing machine.

After removing the plastic very easy just a screwdriver needed you reveal some u shape of metal

covered in copper wire and two leads coming out....

Danish scientist Hans Christian Ørsted discovered in 1820 that electric currents create magnetic fields. British scientist William Sturgeon invented the electromagnet in 1824. His first electromagnet was a horseshoe-shaped piece of iron that was wrapped with about 18 turns of bare copper wire (insulated wire didn't exist yet). The iron was varnished
to insulate it from the windings. When a current was passed through the coil, the iron became magnetized and attracted other pieces of iron; when the current was stopped, it lost magnetization.

Sturgeon displayed its power by showing that although it only weighed
seven ounces (roughly 200 grams), it could lift nine pounds (roughly 4 kilos) when the current of a single-cell battery was applied.

And now a small experiment take another washing machine pump put it on top of the homemade

electromagnet connect the wires, it doesn't matter as long the wires from the washing machine pump are

connected to the wires of the homemade electromagnet.And now just turn the small wheel(nob) of the

washing machine pump.....Amazing....

You will see that the two pieces stay magnetically connected for a long time.

Leedskalnin became interested in the general theory of magnetism. His four pamphlets addressed the interaction of electricity, magnetism and the body; Leedskalnin also included a number of simple experiments to validate his theories.
Contradicting the standard model of electromagnetism, his thesis is based upon the theory that the metal itself is not the magnet and that the real magnets are circulating in the metal. These individual north and south pole magnets are particles smaller than atoms or photons and each particle in the substance was an individual magnet by itself
