Can magnetic lines be straight?
Magnetic field lines can never cross, meaning that the field is unique at any point in space. Magnetic field lines are continuous, forming closed loops without beginning or end. They go from the north pole to the south pole.
What is the gap between two pole pieces and why is it so?
The air gap between the pole pieces and the armature is kept very small to keep the field strength at its highest value. This is due to the reason the flux lines can pass through iron very easily than the air gap.
Why are magnetic field lines curved?
Magnetic field lines are closed curve because for a magnet there are no monopoles i.e., a magnet always has two poles (north pole and south pole) even if it is cut from anywhere between.
What happens to the field lines when two magnets are aligned with opposite poles?
When opposite poles of two magnets are brought together, the magnetic field lines join together and become denser between the poles. This situation is shown in Figure 20.11. A compass placed here would quickly align with the magnetic field and point toward the south pole on the right.
Is magnetic lines of force always a straight line?
False is it. Magnetic lines are not always straight.
Why magnetic field are closed curve why two magnetic field lines never intersect to each other?
(a) The magnetic field lines do not intersect or cross one another. This is due to the fact that the resultant force on a North Pole at any point can be only in one direction. (b) Magnetic field lines are closed curves or forms a closed loop. This is because two magnetic field lines can never intersect.
Why magnetic field lines are known as non terminating curves?
A magnetic field has no sources or sinks (Gauss’s law for magnetism), so its field lines have no start or end: they can only form closed loops, extend to infinity in both directions, or continue indefinitely without ever crossing itself.
Why do not two magnetic field lines intersect each other?
Two magnetic field lines do not intersect each other because if there was point of intersection, The compass needle would point towards 2 directions. Which means that the magnetic field has two different directions, which is not possible.
Why don t the two magnetic lines of force intersect 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 strongest at the Poles?
The magnetic field is strongest at the poles, where the field lines are most concentrated. The magnetic field pattern when two magnets are used is shown in this diagram. Note the different patterns seen when two like poles are used and two opposing poles are used.
What is the magnetic field pattern when two magnets are used?
The magnetic field pattern when two magnets are used is shown in this diagram. Note the different patterns seen when two like poles are used and two opposing poles are used. When magnetic field lines are the same distance apart from each other, we say that the magnetic field is uniform.
What does it mean when the magnetic field is uniform?
When magnetic field lines are the same distance apart from each other, we say that the magnetic field is uniform. This is shown in the diagram:
How does a magnet interact with a moving charge?
Magnetic Field. Interaction of magnetic force and charge – The moving charge interacts with the fixed magnet. The force between them is at a maximum when the velocity of the charge is perpendicular to the magnetic field.
