Magnetic lines of force always originate from the North Pole and end at its the South Pole. Magnetic lines of force are defined as the curved lines which are used for representing the magnetic field.
Where do magnetic field lines originate?
From the properties of bar magnets, we know that the magnetic field lines responsible for the field originate at the north and terminate at the south pole, and are thus closed loops.
Where are magnetic lines of force?
Magnetic field lines exit a magnet near its north pole and enter near its south pole, but inside the magnet B-field lines continue through the magnet from the south pole back to the north.
Who discovered magnetic lines of force?
scientist Michael Faraday
Are magnetic lines of force real?
To describe the phenomena related to magnets, lines are used to depict the force existing in the area surrounding the magnet. These lines are called the magnetic lines of force. These lines do not exist actually, but are imaginary lines that are used to illustrate and describe the pattern of the magnetic field.
Can we see magnetic flux lines?
At each end of a magnet is a pole. These lines of flux (called a vector field) can not be seen by the naked eye, but they can be seen visually by using iron fillings sprinkled onto a sheet of paper or by using a small compass to trace them out.
How magnetic field is created?
Any current (movement of electrical charge) will create a magnetic field. Certain materials are capable of realigning the angular momentum of their electrons, and iron is one of them. When the angular momentum of electrons gets aligned, an external magnetic field is created.
What is a magnetic line of force?
Magnetic lines of force are the lines that depict the magnetic force that exists in the surrounding of the magnet. … The direction of field lines inside the magnet is from the South Pole to the North Pole. Magnetic lines do not intersect with each other.
Where is the magnetic field the weakest?
What statement best describes magnetic fields?
The correct answers are “A magnetic field is the area around a magnet where a force is exerted on certain objects”, “Magnetic field lines spread out of the north end of the magnet” and “Magnetic fields are three-dimensional and resemble a bubble”.
Do the lines of force really exist?
No, they do not exist. Electric field lines are only imaginary. They are the paths along which an imaginary unit charge would move when free.
What material can block a magnetic field?
The short answer is: Any ferromagnetic metal. That is, anything containing iron, nickel or cobalt. Most steels are ferromagnetic metals, and work well for a redirecting shield. Steel is commonly used because it’s inexpensive and widely available.
Can magnetic lines of force cross each other?
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.
Why magnetic lines of force 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.
Why are magnetic lines of force closed?
Magnetic lines form continuous closed loops because magnetic monopole does not exist in nature. We always find magnetic poles – North and South pole which are coupled together in such a way that field lines originating from one pole ends at the another loop, forming a closed loop.
Why do magnetic lines of force move from north to south?
When it comes to magnets, opposites attract. This fact means that the north end of a magnet in a compass is attracted to the south magnetic pole, which lies close to the geographic north pole. Magnetic field lines outside of a permanent magnet always run from the north magnetic pole to the south magnetic pole.
