How do you describe the direction of a magnetic field produced by an electric current?

The magnetic field produced by an electric current is always oriented perpendicular to the direction of the current flow.

How do you describe and determine the direction of a magnetic field produced by an electric current?

Key Points

Another version of the right hand rules can be used to determine the magnetic field direction from a current—point the thumb in the direction of the current, and the fingers curl in the direction of the magnetic field loops created by it.

What is the direction of a magnetic or electric field?

they are produced only by moving charges while electric fields are produced by both moving charges and stationary charges. moving charge is perpendicular to the direction of motion. The direction of the force due to a magnetic field is perpendicular to the direction of motion.

What is direction of magnet?

Magnetic field lines are defined to have the direction that a small compass points when placed at a location. (a) If small compasses are used to map the magnetic field around a bar magnet, they will point in the directions shown: away from the north pole of the magnet, toward the south pole of the magnet.

What is the direction of the magnetic field lines outside any magnet?

North pole to south pole is the direction of magnetic field lines outside a bar-magnet. The magnetic field is the strongest inside the magnetic material. The strongest external magnetic fields are near the poles. A magnetic north pole will attract the south pole of another magnet, and repel a north pole.

How is the direction of magnetic field at a point in a magnetic field?

The direction of a magnetic field at a point is determined by placing a small compass needle. The N – pole of compass indicates the direction of magnetic field at that point.

What is the direction of magnetic field inside the bar magnet?

(a) The direction of magnetic field lines outside a bar-magnet is from North seeking pole to south seeking pole while inside the magnet it is from south to north seeking pole.

What is the direction of magnetic moment?

The direction of the magnetic moment points from the south to north pole of the magnet (inside the magnet). The magnetic field of a magnetic dipole is proportional to its magnetic dipole moment.

How will you describe the magnetic field lines far from the magnet?

If you place a compass near the north pole of a magnet, the north pole of the compass needle will be repelled and point away from the magnet. Thus, the magnetic field lines point away from the north pole of a magnet and toward its south pole.
