This past week, thanks to Laughing Squid and other sources, a lot of people watched and were amazed by this simple demonstration of electromagnetism in action. It is billed as the "world''s simplest electric train," and it is almost certainly the case. Using only a battery, some strong magnets and some (bare) coiled copper wire,
According to Faraday''s law, a changing magnetic field induces an electromotive force (EMF) in a conductor. In an electric motor, this principle is utilized to create a rotating magnetic field that interacts with the magnetic field of the rotor, resulting in continuous motion. The principle of operation can be summarized in a few simple steps:

First, strip one of the ends of one copper wire, and if you have the penny available, then fit the penny into the stripped end. Cover the entire penny with the striped end of the copper wire and make a tight fit. In case you don''t have a penny, use alligator clips to fit the copper wire into the potato in the next step.
Even though a wide range of types of batteries exists with different combinations of materials, all of them use the same principle of the oxidation-reduction reaction an electrochemical cell, spontaneous redox reactions take place in
Find a D battery, or a 1.5 volt battery, and place each end of the wire on an end of the battery so they''re touching. Place pieces of electrical tape or duct tape over each wire end to hold them in place.
It is not moving because the wire is magnetic; it is copper wire, a none magnetic material. The movement of the wire is perpendicular to that of the electric field and the current, so in the illustration above it would be a vertical movement. When the current is switched off, the wire moves back to its original position.

The wire ends are quickly shredded
Pure copper wire is first dissolved into a solution, and an electrolytic reaction deposits the copper ions onto a rotating titanium drum. This results in a uniform copper battery foil, that is tightly controlled to ensure dimensional accuracy and surface finish, optimised for the coating processes used by lithium ion battery manufacturers.
motor shape with the copper wire: i. The copper wire must be touching the positive terminal. ii. The shape of your copper wire MUST be as balanced as possible to stay on the positive terminal of the battery. iii. The copper wire must make contact with the battery—looping it around is the best way. iv. Use caution!

2) Electromagnetic Coil:-It is a coil or spiral wire usually of copper that is located inside the stator. When the current flows from the battery to the coils, the electromagnetic field is produced around the coil. 3) Friction Material:-Friction
Here, an electric current in the copper wire is conducted through the magnetic field around the magnets. This causes a force to arise, which pushes on the copper wire and causes it to move. You have just built a machine that can make something move with the help of an electric current - an electric motor.

Now insert the battery through the top of the spiral winding. And finally, place the pointed end of the spiral winding onto the positive terminal of the battery to watch it spin.
The order of components progressing upwards is metal stand, cylindrical magnet, battery, nut, and either of the copper windings on top. Either copper winding should spin properly, but may require slight adjustment to maintain good contact with both ends of the battery without causing too much friction.
