An electric current flowing through a coil of wire provides the energy needed to create magnetic fields in an electromagnet.
An electric motor typically uses one electromagnet and one permanent magnet to create a magnetic field that interacts to produce motion. The electromagnet's field can be easily controlled by varying the electric current, allowing the motor's speed and direction to be changed. The permanent magnet provides a fixed magnetic field that interacts with the variable field of the electromagnet to generate the rotational force needed for the motor to work.
no
The most basic of electric motors consists of a permanent magnet and an electromagnet. This is not a requirement for all types of electric motors and most modern electric motors do not have permanent magnets. The stator and rotor are the two active elements of a simple electric motor and both have magnetic fields in the various types and designs of simple motors.
The discovery was that increasing the number of wire coils on an electromagnet results in a stronger magnetic field. This relationship was observed through experimentation and measurements of the magnetic field strength produced by different numbers of wire coils on the electromagnet.

The nail in an electromagnet is the core of the electromagnet. It is there to provide the magnetic lines of force a "highway" to get from one end of the coil to the other end through the middle of the coil. The magnetic lines of force "like" the nail because it is a ferromagnetic material. They can travel through it very easily - and they do! The nail also provides the "working end" of the electromagnet. The magnetic field lines emerge from the nail, and then act on what is there. If you are, say, doing a separation experiment removing steel tacks that are mixed in with small brass nails (brads), the tacks will stick to the end of the nail at the "working surface" or the pole of the electromagnet.

Yes. An Iron core electromagnet has a stronger magnetic field then a coil. The magnetic flux is condensed and travels through the iron core with little resistance, while air provides much greater resistance.

convert electrical energy to energy of motion...! the usage of an electromagnet allows us to control the flow of electrons to the electric rotor,thereby allowing us to control the working of the rotor,whereas with a permanent magnet there will be a continuous supply of energy which can be stopped only if the magnet is damaged or heated.
A changing magnetic field induces an electric current and this understanding provides the fundamental ability for converting mechanical energy to electrical energy. Michael Faraday's discovery of electromagnetic induction in 1831, provides the foundation of this knowledge in science shared around the world. Active Kinetic 1 provides an extension to this method by adding oscillation, which completes the necessary variables most notably quoted by Nikola Tesla "energy frequency and vibration". ak1.co/oscillating-induction/
