Magnetism, an aspect of electromagnetism, one of the fundamental forces of nature. Objects such as a bar magnet can influence other magnetic materials, without physically connecting them, because magnetic objects produce a magnetic field. Magnetic fields are usually represented by magnetic flux lines. Magnetic fields influence magnetic materials and also influence charged particles that move through the magnetic field.
No, only when it is moving/changing does electricity produce magnetism.
Also, only when it is moving/changing does magnetism produce electricity.
This is expressed in Maxwell's Equations and is a symmetry of nature.
Yes, magnetism is the force generated by magnets, or magnetic fields.
Static electricity doesn't. But as soon as charge begins to move,
you have an electric current, and current always does.

How do electricity and magnetism produce movement?
When an electric current flows through a wire, it creates a magnetic field around the wire. This magnetic field interacts with other magnetic fields to produce movement, as in the case of an electric motor. In turn, a moving magnet near a wire can induce an electric current to flow through the wire, as in the case of a generator.
If a stationary electron sat inside a stationary magnetic field would the magnetic field cause the electron to move?
No, a stationary electron placed in a stationary magnetic field would not move due to the magnetic field alone. The force experienced by a charged particle in a magnetic field is perpendicular to both the magnetic field and the velocity of the particle. In this case, since the electron is stationary, there is no component of its velocity perpendicular to the magnetic field for the magnetic force to act upon.
What is the connection between magnetism and electricity?
The connection between magnetism and electricity is electromagnetism. An electric current creates a magnetic field, and a changing magnetic field induces an electric current. This relationship forms the basis of many technologies, such as electric motors and generators.
How is magnetic force defined?
Magnetic Forcenounattraction for iron; associated with electric currents as well as magnets; characterized by fields of force [syn: magnetism]
Why does electricity produce magnetic field?
Electricity flowing through a conductor creates a magnetic field due to the movement of electric charges. This phenomenon is described by Maxwell's equations in electromagnetism. The interaction between electric currents and magnetic fields is fundamental to many devices and technologies, including electromagnets, generators, and transformers.
Do electrical currents always produce a magnetic force?
No, electrical currents only produce a magnetic force if they are flowing through a conductor. In a vacuum or in an insulator, electrical currents do not produce a magnetic force.
Why are electrical machines made of magnetic materials?
Because the magnetic force between two magnets can produce electricity because the - and + will try to get to attract each other thus causing electricity
Can a electric current runnng along a wire be used to produce a magnetic force?
Whether or not you use it, there's always a magnetic field surrounding an electric current.When anything that can respond to a magnetic force is brought close enough to the current,it does feel a magnetic force.
What force do electromagnets produce?
Electromagnets produce a magnetic force when an electric current passes through them. This force is the result of the interaction between the magnetic field generated by the current and any nearby magnetic materials or other electromagnets.
Plants with a magnetic force?
Compass plants respond to Earth's magnetic field, but do not produce their own magnetic force.
Are electricity and magnetism the same thing?
Electricity and magnetism are related phenomena that are interconnected through electromagnetic force. Electricity deals with the flow of electric charge, while magnetism involves the interaction of magnetic fields. They are distinct concepts but are closely linked in the electromagnetic force that governs their behavior.
Did magnetic force always exits?
Yes. Magnetism is a force that has always existed.
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.
What exerts the magnetic force?
The magnetic force is exerted by moving electric charges, such as electrons. When these charges move, they create a magnetic field. This magnetic field can interact with other moving charges to produce a force.
Why is there a limit to the magnetic force that a material can produce?
because there is a magnetic field round an object
How do electricity and magnetism produce movement?
When an electric current flows through a wire, it creates a magnetic field around the wire. This magnetic field interacts with other magnetic fields to produce movement, as in the case of an electric motor. In turn, a moving magnet near a wire can induce an electric current to flow through the wire, as in the case of a generator.
How do magnets help generator produce electricity?
Magnets would have magnetic flux around. As a coil linked with this magnetic flux is rotated such that the flux would change then an electro motive force is induced. This is the way in which generator functions.
