Bar magnets are already magnetized. They don't need to add wire and electricity.

Are electricity and magnetism the same thing?
Electricity and magnetism are similar but yet different. They are both able to make a form of each other. If electricity charges are pulled at a great force they will be able to create a type of magnetic force. Magnets are able to produce forms of electricity when their pulls are changed.
How do household goods use magnets?
Speakers and motors use magnets. Using electricity, the electromagnets create a magnetic force which reacts against the permanent magnets in these devices, thus creating motion. Magnets are used in cabinet latches to help them to stay closed. Screwdriver tips are sometimes magnetized to help hold the screw on the end or to help retrieve a dropped screw. Magnets are often used to hold things onto metal objects. Refrigerator magnets are one example. Common objects may have magnets attached to hold them onto refrigerators and other metal objects like lockers and metal cabinets.
what is responsible for electricity?
Electricity is the movement of electrons between atoms. It is inexorably linked to magnetism (and light) - moving electrons create a magnetic field and a magnetic field will cause electrons to move in a conductor and when electrons lose energy light is created.
Why do not magnets stick in human?
Magnetic metals especially Iron, Nickel and Cobalt are only found in microscopic quantities in humans. As a result magnets will not stick to normal healthy humans.
How do magnetism and eletricity work together?
Electricity and magnetism can create each other: Electricity flowing in a wire projects a magnetic field around the wire. Electromagnets, solenoids and motors are examples of this. Magnetic lines of force cutting across a wire induces an electric current in the wire. Generators and alternators are examples of this.
What do magnets have to with electricity?
Faraday showed that a wire passing through a magnetic field will produce electricity. This is how a generator works. Many windings of wire on an armature spin in a magnetic field. This makes electricity.
How do hydroelectric magnets create electricity?
There is no such thing as a hydroelectric magnet, but perhaps you mean how do hydroelectric generators create electricity? Generators work in a way opposite to electric motors. In this generator, a stream of water flows past the vanes of a turbine and causes the turbine to spin. The turbine causes an armature with magnets to rotate. The consequent rotating magnetic field moves past conductive coils of wire surrounding the armature, and as you may know, current is generated when a conductive wire is exposed to a moving magnetic field.

Can magnets conduct electricity?
Some magnets conduct electricity quite well. Others are pretty good insulators. If the magnet is made from metal, chances are that it will be a pretty good electrical conductor. If it is a ceramic magnet or one where magnetic particles are suspended in a non-conductive medium (like those flexible rubber fridge magnets that businesses like to distribute) then the magnet will usually be a very poor electrical conductor.
How can you create motion using electricity?
Motion is most often created from electricity by the use of a motor, or magnetic action. Within an electric motor a series of magnets or electromagnets are energized to allow the fundamental parts to spin on an axis.
How do magnets help create electricity?
If a conductor - such as a wire - moves through a magnetic field, a voltage is produced in the conductor. This may cause a current (if the wire is connected to an external circuit). This effect is used in generators to generate electricity.
Why does an electro magnet work?
Magnetizm and electricity are closly related. An electric current can produce its own magnetic field. Electricity can also be used to create a magnet. such magnets are called electromagnets. The electricity flowing through the tight coils of wire creates a strong magnetic fields from one end to the other. By running the electric current through a wire you can create a magnetic field. The force lines up all the magnetic particles in the nail and turns it into a magnet. The more coils of wire there are , the stronger the magnetic force.
Dose electricity create magnets or do magnets create eletricity?
Yes.A moving magnet inside a coil of wire creates electricity, however, a magnetic flux is produced by an electrical current. Many experiments are described on the internet regarding a current and iron filings to determine the magnetic flux.

What is magnetic in electromagneticism?
Maxwell's equations state that electric fields create magnetic fields, and vice versa. If you have a current, you have a magnetic field. If you have magnets, you have an electric field.
How do magnets and wire make electricity?
Any time a conductor passes through a magnetic field you create electricity. It may be infinitesimally small, but it is there. It is caused by the magnetic field forcing electrons in the conductor to move. It is called electromotive force(emf) and is measured in volts. If there is no circuit, which is a path for the electrons to flow, it is not useable. Generators, or the alternator in your car, are simply ways to create enough emf to be useable.
What is Electromagnetic Suspension?
It is when opposite ends of the magnets create a magnetic field that makes the object levitate.
