Why are magnetic lines continuous?
Magnetic lines are imaginary lines. Within the magnet, they move from south pole to north pole and outside the magnet they move from north pole to south pole. Hence, magnetic lines form continuous closed loops.
Are magnetic lines of force continuous or discontinuous?
(2) The simplest magnetic structure is characterized by a vector whereas in electricity it is a scalar quantity q. (3) Electric lines of force are discontinuous whereas magnetic lines of force are continuous.
Are magnetic field lines are endless?
The magnetic field lines are closed curved. The conventions of magnetic field lines are emerge from North pole and merge at the South pole and inside the magnet its direction is from South pole to the North pole. Hence, they form a closed continuous loop. This is why the magnetic lines of force are endless.
Is magnetic line of force a continuous curve?
Magnetic field lines represent continuous curves that originate at the north pole of a magnet and end at the south pole. Inside the magnet they travel from the south pole to the north pole. … Therefore, the magnetic field lines are continuous and form closed loops.
Are electric field lines always continuous?
Option A-No, the electric field is not always continuous. … Note- The electric field because of any charge will be continuous, if there is no other charge in the medium. It will be discontinuous if there is a charge at that viable point.
What is the difference between electric and magnetic lines of force?
Answer. Electrical field lines induces on a positive charge and diminishes in a negative charge whereas a magnetic field line starts at the north pole and ends at the south pole. Electric field and magnetic field lines are mutually perpendicular to each other.
Why do magnetic lines form continuous closed loops?
i Magnetic lines of force form continuous closed loops because a magnet is always a dipole and as a result the net magnetic flux of a magnet is always zero. ii When a diamagnetic substance is placed in an external magnetic field a feeble magnetism is induced in opposite direction.
Why are magnetic lines of force closed?
The direction of a magnetic line at a point gives the direction of the magnetic force at the north pole placed at that point. Since the direction of the magnetic field line is the direction of the force at the north pole. … Thus the magnetic field lines are closed.
Why do magnetic lines of force form continuous closed loops?
(i) Magnetic lines of force form continuous closed loops because a magnet is always a dipole and as a result, the net magnetic flux of a magnet is always zero. (ii) When a diamagnetic substance is placed in an external magnetic field, a feeble magnetism is induced in opposite direction.
Are magnetic lines of force always closed?
The lines of force always originate from the north pole and get into the south pole. … The interesting thing about these magnetic lines of force is that they never come across each other and they always start at the north pole and terminate at the south pole. This is the reason why they always form closed loops.
Can magnetic lines of force pass through vacuum?
Do not pass through vacuum.
Is magnetic field lines form closed loops?
Magnetic field lines are continuous, forming closed loops without beginning or end. They go from the north pole to the south pole.
Are magnetic field lines imaginary?
Magnetic field lines are imaginary lines that represent magnetic fields. It gives direction of magnetic force. … Magnetic field lines are like streamlines in fluid flow, they represent something continuous, and a different resolution would show more or fewer lines.
Why do magnetic field lines not form closed loops?
Electric field lines start (or diverge) from the +ve (positive) charge and terminate (or converge) on negative charge. If the electric field lines form a closed loop, these lines must originate and terminate on the same charge which is not possible because electric field lines always move from positive to negative.
Why do two magnetic lines never intersect?
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.
Why are field lines imaginary?
An electric field line is an imaginary line or curve drawn through a region of empty space so that its tangent at any point is in the direction of the electric field vector at that point. The relative closeness of the lines at some place gives an idea about the intensity of electric field at that point.
Which is not true for magnetic field lines?
Detailed Solution
Magnetic field lines appear to emerge or start from the north pole and merge or terminate at the south pole. Inside the magnet, the direction of the magnetic field lines is from the south pole to the north pole. Magnetic field lines never intersect with each other.
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.
Can electric field lines cross each other?
Electric field lines never cross each other. Electric field lines are most dense around objects with the greatest amount of charge. At locations where electric field lines meet the surface of an object, the lines are perpendicular to the surface.
What does Fleming left hand rule state?
Answer: Fleming’s Left hand rule states that if we arrange our thumb, forefinger and middle finger of the left hand right angles to each other, then the thumb points towards the direction of the magnetic force, the forefinger points towards the direction of magnetic field and the middle finger points towards the …
What will happen if you break a magnet in half?
If you break a bar magnet in half, each half will have a north and south pole, even if you break it in half many of times. The north poles of two magnets will repel each other, as will their south poles. On the other hand, a north pole and a south pole will attract each other.
