A magnetic conductor is a material that supports free movement of magnetic charge (magnetic monopoles), similar to an electric conductor that allows free movement of electric charges. On average the net charge is neutral. Of course, magnetic monopoles do not exist, but clever engineering can produce close to the same effects. Importantly, magnetic conductors have hugely different boundary conditions from electric conductors in electromagnetics and physics. A major research breakthrough in demonstration of wideband magnetic conductors was published in 2011 in "Wideband Artificial Magnetic Conductors Loaded With Non-Foster Negative Inductors" by Gregoire, D.J. ; HRL Labs., LLC, Malibu, CA, USA ; White, C.R. ; Colburn, J.S..

What is the relationship between magnetic fields and electricity?
-- A current flowing through a conductor creates a magnetic field around the conductor. -- Moving a conductor through a constant magnetic field creates a current in the conductor. -- If there's a conductor sitting motionless in a magnetic field, a current flows in the conductor whenever the strength or direction of the magnetic field changes.
What does a changing magnetic field induce in a conductor?
A changing magnetic field induces an electric current in a conductor.
What three things needed to complete magnetic induction?
A changing magnetic field A conductor or coil of wire Movement between the magnetic field and the conductor (relative motion)
Force on a current-carrying conductor?
When a current-carrying conductor is placed in a magnetic field, a force is exerted on the conductor due to the interaction between the magnetic field and the current. This force is known as the magnetic Lorentz force and its direction is perpendicular to both the magnetic field and the current flow. The magnitude of the force depends on the strength of the magnetic field, the current flowing through the conductor, and the length of the conductor exposed to the magnetic field.
What is the force on a circular conductor in a magnetic field?
magnetic force
How is the movement of electrons in a conductor related to the formation of magnetic field?
When electrons move through a conductor, they create a flow of electrical current. This flow of current generates a magnetic field around the conductor in accordance with Ampere's law. The strength of the magnetic field is directly related to the magnitude of the current and the distance from the conductor.
When lines of force are cut by a conductor you have magnetic?
Presumably, you are asking what happens when a conductor 'cuts' lines of magnetic flux? If so, then a voltage is induced across the ends of that conductor.
Can a static magnetic field exist in a good conductor?
A static magnetic field can exist in a good conductor. When the conductor carries current, it produces the flux which can exist inside the conductor. Due to this flux, magnetic field and intensity at a point inside the good conductor.
What does a conductor do in a magnetic field when current is suddenly passed through it?
When current is suddenly passed through a conductor in a magnetic field, it experiences a force due to the interaction between the magnetic field and the current. This force causes the conductor to move, resulting in electromagnetic induction and the generation of an electric current in the conductor.
What is the magnetic effects of electrical current?
When an electrical current flows through a conductor, it creates a magnetic field around the conductor. This phenomenon is known as electromagnetism. The strength of the magnetic field is directly proportional to the current flowing through the conductor.
Dc current having magnetic field?
When a direct current (DC) flows through a conductor, it generates a magnetic field around the conductor. This phenomenon is described by Ampere's law, which states that a magnetic field is produced around a current-carrying conductor. The strength of the magnetic field is directly proportional to the current flowing through the conductor.
Moving a conductor through a magnetic field a voltage is induced in the conductor is called what type of induction?
Moving a conductor through a magnetic field will produce alternatinc current (AC).
