You can detect it by watching a compass needle, if that's what you mean.

Do magnetic field lines close together indicate a weaker magnetic field?

No, magnetic field lines close together indicate a stronger magnetic field, while magnetic field lines farther apart indicate a weaker magnetic field. The density of field lines represents the strength of the magnetic field in that region.


Do field lines need that are close together indicate a weaker magnetic field?

No, field lines that are close together indicate a stronger magnetic field, not a weaker one. The density of field lines represents the strength of the magnetic field in that region.


What do the lines around a bar magnet?

The lines around a bar magnet represent the magnetic field. They indicate the direction in which a magnetic north pole would move if placed in the field. The density of the lines indicates the strength of the magnetic field.


What is the diagram of a magnetic field and how does it illustrate the direction and strength of the magnetic field lines?

A magnetic field diagram shows the direction and strength of magnetic field lines around a magnet or current-carrying wire. The lines indicate the direction a compass needle would point if placed in the field. The density of the lines represents the strength of the magnetic field, with closer lines indicating stronger fields.


What correctly describes magnetic field lines?

The list of choices submitted with the question containsno correct description of magnetic field lines.


What does crowding of magnetic field lines indicate?

Crowding of magnetic field lines indicates a stronger magnetic field in that area. The density of magnetic field lines is directly related to the strength of the magnetic field in a particular region. This can be observed in areas near magnetic poles or strong magnets.


What does the magnetic quantum number indicate about an electron's orientation in a magnetic field?

The magnetic quantum number indicates the orientation of an electron's magnetic moment in a magnetic field. It helps determine the direction in which the electron will align itself within the field.


What does a magnetic field around a planet indicate?

That it has a metal core.


A device that uses the Earth's magnetic field to indicate which way North is?

That is called a magnetic compass.


Region around a magnet in which magnetic force can act?

Magnetic freild


What do bands of rock on the seafloor showing alternating magnetic orientation indicate about the earths magnetic field?

Bands of rock on the seafloor showing alternating magnetic orientation indicate times when the Earth's magnetic field has reversed. These bands are created as new oceanic crust forms at mid-ocean ridges and records the direction of the Earth's magnetic field at the time of its formation. Studying these bands provides insight into the history of Earth's magnetic field reversals.


What was a swinging magnet used for?

A swinging magnet was often used in old-fashioned compasses to indicate direction based on Earth's magnetic field. The magnet would align itself with the Earth's magnetic field, pointing towards the magnetic North Pole.
