Passing an electric current through coiled wires will create an electro-magnet, whose magnetism can be increased if iron or some other magnetic rod is used as a core.
A simple electromagnet can be constructed by wrapping a wire around a wooden pencil and attaching a battery to the two ends f the wire. The coil will have magnetic properties even if the pencil is removed. If you use a large nail rather than a pencil the nail will become magnetised while current is flowing, and to a lessor degree even when the current is stopped.
The interactions and relationships between electricity and magnetism form the basis of both generators, alternators, electric dynamos, electric motors, speakers, and even telephones.

What do electric and magnetic fields contain and transport?
Electric and magnetic fields contain energy and information. They transport this energy and information through space. In the case of electric fields, they are generated by stationary electric charges and transport energy and information by interacting with other charges. Magnetic fields, on the other hand, are generated by moving charges or changing electric fields and also transport energy and information through their interactions with other magnetic fields or moving charges.
What happens with the energy associated to the magnetic field of a coil with electric current if the electric current is turned off?
The magnetic field or energy associated with the magnetic field will no longer be generated if the current is turned off.
How does a generator convert mechanical energy into electrical energy?
An electric generator is a device used to convert mechanical energy into electrical energy, Which is used to convert mechanical energy into electrical energy. The generator is based on the principle of "electromagnetic induction" discovered in 1831 by Michael Faraday, a British scientist. Faraday discovered that if an electric conductor, like a copper wire, is moved through a magnetic field, electric current will flow (be induced) in the conductor. So the mechanical energy of the moving wire is converted into the electric energy of the current that flows in the wire.
An electric motor converts electrical energy to potential energy?
They don't. An electric motor is designed to convert electrical energy to kinetic energy, not the other way round. A device that converts kinetic energy to electrical energy is called a generator or a dynamo. Sometimes the same device can do both things (convert in both directions), but since the device is especially optimized for one function, it may not be very good at the other one.
Device that produces current by moving a magnetic field across a wire?
This device is called a generator. When a magnetic field is moved across a wire, it induces a flow of electrons in the wire, creating an electric current. Generators are commonly used to convert mechanical energy into electrical energy in power plants and electric generators.
What does an electric motor use an electromagnet to do?
An electric motor uses an electromagnet to convert electrical energy into mechanical energy. The electromagnet generates a magnetic field that interacts with other magnetic fields to produce motion, causing the motor to run.
Can an electromagnet produce electric energy?
No, an electromagnet generates a magnetic field when an electric current passes through it but it does not produce electric energy on its own. Electric energy is typically produced by generators that convert mechanical energy into electrical energy through electromagnetic induction.
What are the devices that convert magnetic energy into electrical energy?
Magnetic energy and electric energy are virtually the same according to Maxwell's equations. Which shows maxwell doesnt know what he is talking about then, they are two very distinc energies. Im not sure myself about the ways to convert them I am looking into it at this very moment.
What does an electric motor use an electromagnetic to do?
Convert electrical energy to energy of motion...
Is electric and electro magnetic energy the same thing?
While electric energy refers to the flow of electric charge, electromagnetic energy encompasses both electric and magnetic fields that propagate through space as electromagnetic waves. In essence, electric energy is a component of electromagnetic energy, alongside magnetic energy.
How does an electric generator work to convert mechanical energy into electrical energy?
An electric generator works by using a magnet and a coil of wire to convert mechanical energy into electrical energy. When the coil of wire rotates within the magnetic field created by the magnet, it generates an electric current. This current can then be used to power electrical devices.
How can kinetic energy be transformed into electric energy?
Kinetic energy can be transformed into electric energy through the use of devices called generators. Generators convert the mechanical energy from motion into electrical energy through electromagnetic induction. When a conductor moves through a magnetic field, it creates an electric current, which can then be harnessed and used as electric energy.
What is the difference between energy conversion that takes place in an electric motor with the conversion that takes place in a generator?
In an electric motor, electrical energy is converted into mechanical energy to produce motion. In a generator, mechanical energy is converted into electrical energy by rotating a coil within a magnetic field. Essentially, electric motors convert electrical energy into mechanical energy, while generators convert mechanical energy into electrical energy.
In an electric motor a magnetic field causes a current carrying LOOP to spin true or False?
True. In an electric motor, a magnetic field causes a current-carrying loop to experience a torque that makes it spin. This spinning motion is the basis of how electric motors convert electrical energy into mechanical energy.
What energy produces a magnetic field?
electric energy
Does a electric motor convert chemical energy to mechanical energy?
No, an electric motor does not convert chemical energy to mechanical energy. Electric motors convert electrical energy into mechanical energy by using electromagnetic fields to create motion.
How does a battery convert energy?
The two sides, the anode and the cathode contain opposite charges. The difference between the charges determines the potential of the battery. The potential can be described as stored energy, called electric potential energy. When the anode and cathode are connected by a circuit, the difference between the charges diminishes, which means this stored energy is being lost somehow. Different loads can harness this energy and convert it to another. Electric motors use magnetic fields induced by the electric current, which means that the electric potential energy is being converted into magnetic potential energy, which is immediately converted into kinetic energy, while incandescent light bulbs use electrical resistance of a filament to convert the electric potential, into a combination of infrared and visible light energy.
