What do the arrows on magnetic field lines show?

What do the arrows on magnetic field lines show?

The arrows represent invisible lines of force, known as magnetic field lines. They indicate the direction a compass arrow lies – pointing north–south. This difference is called magnetic declination.

What do the lines and arrows show about the direction of the force of the magnet on magnetic objects or on other magnets?

Often magnetic field patterns are presented as lines of force and shown as arrows pointing away from the north-seeking-pole and towards the south-seeking-pole. More accurately, magnetic field lines show the direction in which the north-seeking-pole of a magnet would be pushed or pulled.

Why must you add arrows to the magnetic field line drawings?

Magnetic field lines spread out from one pole, curve around the magnet, and return to the other pole. Arrows point from the north pole toward the south pole. Diagrams should have field lines spaced so as to indicate field strength and with arrows showing field direction.

What does the direction of a magnetic field show?

the lines have arrowheads to show the direction of the magnetic field; the direction of a magnetic field at a point is the direction of the force on a north pole at that point; magnetic field lines point from the north pole of the magnet to its south pole.

What is the direction of the magnetic lines of force outside the magnet?

North pole to south pole is the direction of magnetic field lines outside a bar-magnet.

Where is the strongest attraction force of the magnet?

north pole
The magnetic field of a bar magnet is strongest at either pole of the magnet. It is equally strong at the north pole when compared with the south pole. The force is weaker in the middle of the magnet and halfway between the pole and the center.

Why can’t two magnetic field lines cross each other?

The magnetic field lines never intersect each other because if two or more lines intersect each other than it means that at that point of intersection, the magnetic field has two directions at the same point. This is not possible for a magnetic field to point in more than one direction at the same point.

Where is the magnetic field the strongest?

the poles
It is strongest at the poles. So, what are magnetic poles? Magnetic poles are opposite ends of a magnet where the magnetic field is strongest.

What material can block a magnetic field?

Magnetic fields cannot be blocked, only redirected. The only materials that will redirect magnetic fields are materials that are ferromagnetic (attracted to magnets), such as iron, steel (which contains iron), cobalt, and nickel.
