Magnetic induction. If you have conductor, then there are these free electrons bouncing back and forth between the atoms. They move in random directions and there is no unified movement which we could detect as electric current.
From the Lorentz force of a charge moving through a magnetic field, we have the force as F = qv x B. Where v and B are vectors. The force will be perpendicular to both the velocity and the B field. Its magnitude is qvB*sin(Θ). So if your conductor is moving in a magnetic field, then those free electrons will experience a force accelerating them in a perpendicular direction.
To give a sense of this, if the wire is laying flat on a paper running left and right, and the magnetic field lines are coming up out of the paper, if you move the wire in the up direction (on the page) then the electrons will be forced to move towards the right (along the conductor).

What is the relationship between magnetic force and distance?
-- 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.
When a conductor is moved in a magnetic field a voltage will be induced on the conductor. However current won't flow through the conductor unless the conductor is?
moving
What actually happens when current passes through conductor?
if the cuurent is less we can save the condutor if current is high nothing in our hand we need to pra for him
What is the eddycurrent principle?
there is a permanent magnet and a conductor (metal)in relation. when the conductor is moved by cutting the magnetic relay. there will be a charge in the conductor. this is the eddy current priciple
What happens when electric current passes through a coil of wire?
A magnetic field generates around the wire.
Why does the current carrying conductor experiences a force when it is placed in magnetic field state Fleming's left hand rule?
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.
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.
How do magnets magnetic fields electric currents and metals connect?
Well when an electric current flows through a conductor a magnetic field is produced. And a changing magnetic flux through a conductor produces a current in the conductor.
When is the force experienced by current carrying conductor placed in a magnetic field strongest?
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.
Can Magnetism cause an electric current to flow in a conductor?
Yes, a MOVING magnetic field will cause electric current to flow in a conductor. Conversely an electric current flowing in a conductor will cause a magnetic field.
What does a conductor do in a magnetic field when current is suddenly passed through it?
the conductor has to be moved.
When there is no current passing through a conductor you say magnetic field is zero but in a conductor charges are in motion then why is there no magnetic field?
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.
How induced current is produce?
when a conductor moves accross a magnetic field or when magnetic field moves with respect to a stationary conductor for current to be induced, there must be relative motion between the coil and the magnetic.

What is a fluxmeter?
meter that measures magnetic flux by the current it generates in a coil
How electric current causes magnetic field around conductor?
Electric current causes magnetic field around conductor by producing a moving electric charges and the intrinsic magnetic moments of an elementary particles that is associated with a fundamental quantum property.
Current passing through a conductor is increased from 10 A to 15 A. This decreases the strength of the magnetic field produced by the conductor.?
No. More current will result in more magnetic field.
