Electric motor and loud speakers are the two devices that uses current carrying conductor and magnetic field.
-- 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.
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.
The force experienced by a current carrying conductor placed in a magnetic field is strongest when that conductor is placed perpendicularly to the magnetic field.
how is the movement of electrons in a conductor related to the formation of a magnetic field
magnetic force
When the conductor,magnetic field and motion are perpendicular to each other
The force on current carrying conductor kept in a magnetic field is given by the expression F = B I L sin@ So the force becomes zero when the current carrying conductor is kept parallel to the magnetic field direction and becomes maximum when the current direction is normal to the magnetic field direction. Ok now why does a force exist on the current carrying conductor? As current flows through a conductor magnetic lines are formed aroung the conductor. This magnetic field gets interaction with the external field and so a force comes into the scene.
-- 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.
Moving a conductor through a magnetic field will produce alternatinc current (AC).
Circular magnetic field will create around the conductor.
We call it induction when we pass a conductor through a magnetic field to produce voltage.
When there is no current passing through a conductor, charges are stilll in motion, but they are disorganized and not flowing. The magnetic fields by all of those random movements cancel each other out. That is why there is no magnetic field in a conductor with no current, even though there is movement in the charges.
