Magnetic field lines
make closed rings for single magnetic poles that don’t exist
, unlike an electric charge. Therefore, these lines always form closed loops and option(B) is correct. Note: Magnetic field lines are imaginary lines that describe magnetic fields. It provides the path of magnetic force.
Which of the following statement about magnetic field lines is true?
Magnetic field lines
make closed rings for single magnetic poles that don’t exist
, unlike an electric charge. Therefore, these lines always form closed loops and option(B) is correct. Note: Magnetic field lines are imaginary lines that describe magnetic fields. It provides the path of magnetic force.
Which of the following is correct about magnetic field lines?
Q. Which of the following is correct about magnetic field lines? Notes:
The magnetic field lines are closed curves
. The relative strength of the magnetic field is shown by the degree of closeness of the field lines.
Which of the following statement about magnetic field lines is not correct?
Outside the magnet, magnetic field lines go from south to north pole of the magnet is not the correct statement regarding magnetic field. Explanation: The two
magnetic field lines never intersect each other
.
Which of the following statements is correct about magnetic field strength?
Relative strength of magnetic field is shown by
the degree of closeness of the field lines
. This is mainly because of the magnetic flux present. Hence D is also correct.
Where is the magnetic field strongest on a magnet?
the magnetic field lines never cross each other. the closer the lines, the stronger the magnetic field (so the magnetic field from a bar magnet is strongest
closest to the poles
)
What is intensity of magnetic field?
The Magnetic Field Intensity or Magnetic Field Strength is
a ratio of the magnetomotive force needed to create a certain Flux Density within a particular material per unit length of that material
.In other words, Magnetic field intensity is the magnetic induction force acting on a unit magnetic pole.
Who discovered the magnetic effects of current?
The magnetic effect of electric current was discovered by
Hans Christian Oersted
in the year 1982.
Which of the following is correct about magnetic monopole?
Since the
magnetic monopole does not exist
, they do not have monopole momentum. The electric charge has the angular momentum and not the magnetic monopole. So, the only correct answer is option B.
Which is not a property of magnetic lines?
Magnetic lines of force are closed curves. Outside the magnet their direction is from north pole to south pole and inside the magnet these are from south to north pole. These lines do not
intersect
, because if they do so then it would mean two value of magnetic field at a single point, which is not possible.
Which of the following statement is incorrect about the magnetic field?
Answer:
C is incorrect
AnD THE RIGHT ANSWER IS –if magnetic field lines are parallel and equidistant they represent a uniform magnetic field.
Which of the following is intensity of magnetic field?
H
is known as intensity of magnetic field.
What is magnetic field lines in physics?
Magnetic field lines are
a visual tool used to represent magnetic fields
. They describe the direction of the magnetic force on a north monopole at any given position. … One useful analogy is the close connection between magnetic monopoles and electric charges.
What is magnetic flux density simple definition?
magnetic flux density.
A vector quantity measuring the strength and direction of the magnetic field around a magnet or an electric current
. Magnetic flux density is equal to magnetic field strength times the magnetic permeability in the region in which the field exists.
What is H in magnetic field?
The definition of H is
H = B/μ − M
, where B is the magnetic flux density, a measure of the actual magnetic field within a material considered as a concentration of magnetic field lines, or flux, per unit cross-sectional area; μ is the magnetic permeability; and M is the magnetization. …
What is the basic source of magnetism?
The source of magnetism is
the electric charges
. The movement of the electric charge causes magnetism. Substances are made from tiny atoms. These atoms have protons, electrons and neutrons.
