What flows through a circuit and causes a magnetic field?
An electric current flowing through a circuit causes a magnetic field. This is due to the movement of electric charges, usually electrons, in the circuit. The magnetic field produced is perpendicular to the direction of the current flow.
Why electromagnets work?
When you wrap the wire around the nail, make certain that you wrap the wire all in one direction. You need to do this because the direction of a magnet field depends on the direction of the electric current creating it. The movement of electric charges creates a magnetic field. If you could see the magnetic field around a wire that has electricity flowing through it, it would look like a series of circles around the wire. If an electric current is flowing directly towards you, the magnetic field created by it circles around the wire in a counter-clockwise direction. If the direction of the electric current is reversed, the magnetic field reverses also and circles the wire in a clockwise direction. If you wrap some of the wire around the nail in one direction and some of the wire in the other direction, the magnetic fields from the different sections fight each other and cancel out, reducing the strength of your magnet.How_does_a_electromagnet_work
Suppose that you're facing a straight current-carrying conductor and the current is flowing toward you. The lines of magnetic force at any point in the magnetic field will act in?
A clockwise direction
How do you decide the 'Direction of Rotation' of a magnetic field?
There is a convenient rule called the "right hand grip rule":If you grip your right hand around the electric conductor with your thumb pointing in the direction the current is flowing, the magnetic field rotates in the direction your remaining fingers are pointing.See related Wikipedia link for an illustration.
The force on an electron moving in a magnetic field will be the largest when its direction is?
perpendicular to the magnetic field direction
Could a magnetic field be electrons flowing through power lines?
A magnetic field is caused by flowing currents, but the field lines are not directly related to the flow of electrons or other charged particles. They are simply an abstraction that tells you where the magnetic attraction is strongest, and in what direction it goes.
Do all metals respond to magnet?
Magnetism in metals is due to electrons flowing in the same direction, causing a magnetic field. Not all metals produce a magnetic field.
What is the direction of the magnetic field if the current is directed upward or downward?
The direction of the magnetic field is counterclockwise or clockwise. For a current flowing in a wire you can use the "left hand rule" If you take your left hand and have the thumb point in direction of electron flow in the wire, the fingers wrapped around the wire will show the direction of the magnetic field by the direction the fingers are pointed..
Which direction does magnetic fields flow?
I think it is a mistake to refer to magnetic field 'flowing. Magnetic fields just are, they can change, and these disturbances might move in space, but the field itself does not flow. That being said, and assuming you meant to ask in which direction a magnetic field points the answer is that a magnetic field points towards the south pole of a magnet and away from the north pole. A magnetic field cannot be divergent (i.e. there are no sources) and any field line must be closed.
How does electromagnet works?
by running electric current all through a wire a magnetic field is created
What flows through a circuit and causes a magnetic field?
An electric current flowing through a circuit causes a magnetic field. This is due to the movement of electric charges, usually electrons, in the circuit. The magnetic field produced is perpendicular to the direction of the current flow.
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.

When and magnetic fields exist its called an electromagnetic field?
A temporary magnetic field created by a flowing electrical current is an electromagnetic field. Stop the current from flowing, it goes away.

What is resion of Earth magnetic field?
The Earth's magnetic field is the result of electrical currents flowing in the earth.
