The magnetic field lines show the direction in which the magnetic force is acting at any particular point. The density of the magnetic field lines shows the strength of the magnetic force acting. If the lines are close together the magnetic force is great, if the lines are spread out the force is weak.
Similarly one may ask, how do magnetic field lines work?
All magnets have north and south poles. Opposite poles are attracted to each other, while the same poles repel each other. When you rub a piece of iron along a magnet, the north-seeking poles of the atoms in the iron line up in the same direction. The force generated by the aligned atoms creates a magnetic field.
Secondly, what are magnetic lines of force 7?
Magnetic lines of force are the lines that depict the magnetic force that exists in the surrounding of the magnet. The properties of magnetic lines of force are as follows. Magnetic field lines emerge from the north pole and merge at the south pole.
What are the magnetic field lines Class 10?
The path along which north pole moves in a magnetic field is called magnetic lines of force or magnetic field line. They show the direction and strength of magnetic field. If magnetic field lines are very close to each other in a particular region,then the strength of magnetic field in that region,is very large.
What are the properties of magnetic lines of force?
General Properties of Magnetic Lines of Force
- They seek the path of least resistance between opposite magnetic poles. …
- They never cross one another.
- They all have the same strength.
- Their density decreases (they spread out) when they move from an area of higher permeability to an area of lower permeability.
What is line of force explain?
line of force, in physics, path followed by an electric charge free to move in an electric field or a mass free to move in a gravitational field, or generally any appropriate test particle in a given force field.
What is magnetic field line force?
Magnetic Lines of Force is a an imaginary line representing the direction of magnetic field such that the tangent at any point is the direction of the field vector at that point.
What is the formula for magnetic field lines?
We are given the charge, its velocity, and the magnetic field strength and direction. We can thus use the equation →F=q→v×→B or F=qvBsinθ to calculate the force.
