How is the left-hand rule related to current and magnetic field?

It is related to the flow of electrons in a conductor through aseparate magnetic field. If you point your index finger straight place your thumb up and place your middle finger at a 90 degree angle to the other two (unless you are really double jointed there is only one way to do it.). The direction of current and your wire is the middle finger the direction of magnetic plane pointing north is your index finger and the direction of force is your thumb.
There is also the right hand rule. If you look at your right hand with your thumb up and fingers curved, If you held a piece of wire in your hand with the current traveling along the direction of your thumb the magnetic field would rotate in the direction of your fingers.

Is there a magnetic field around current carrying conductors?
yes.magnetic field present around the conductor.current and magnetic fields are inter related..with current we can produce magnetic field and vice versa
What is produced around a wire that has a current?
Magnetic field.
When does an electromagnet produce a magnetic field?
A magnetic field is generated whenever a current is passing through a wire.
If a wire with no current passes a magnetic field of flux will voltage be induced into the wire?
Yes, for as long as the magnetic field is moving along the conductor. A static magnetic field will not induce current, a dynamic field is required.
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.

Magnetism and an electric current are related because?
they both produce a magnetic field :)
Does ac current produce magnetic field?
Yes; any current produces a magnetic field, an AC current will produce an alternating magnetic field. If the current (and therefore the magnetic field) changes quickly, you may not be able to detect it with a compass needle, for example.
What happens to the magnetic field if the current in the wire increases?
If the current in the wire increases, the magnetic field also increases.
What is an electrical current that produces a magnetic field?
The deflection of a magnetic compass in the presence of an electric current, is evidence that an electric current produces a magnetic field.
What is produced around a wire that has a current?
Magnetic field.
What is evidence that an electrical current produces a magnetic field?
The deflection of a magnetic compass in the presence of an electric current, is evidence that an electric current produces a magnetic field.
What statements describes the result of reversing the current in a current-carrying in a magnetic field?
When the current is reverted, the magnetic field will also be reverted.
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 can you turn off a magnetic field by a current?
If the magnetic field is caused only by a current, you can turn the current off.If you have another magnetic field, for example due to a permanent magnet, with a current you can create a magnetic field that counters the first one. But that will only work in certain regions in space; you can't cancel such a magnetic field everywhere in space.
Which happens to the magnetic field of a wire when you change the direction of the current in the wire The magnetic field?
The magnetic field collapses to zero, then builds up again for the current in the opposite direction.
What is the purpose of a magnetic field produced by charges in a current?
Depends whether Direct Current or Alternating Current. Only Alternating Current produces magnetic field.
