yes, they pass through vacuum
Lines of Force
Yes. Magnetic lines of force penetrate paper with little to no difficulty.
Lines of magnetic force are a human device for imagining them. There are no lines as such. The lines we draw are contour lines, analogous to lines of equal force. As to your question, the Magnetosphere is possibly that which you seek.
A magnetic Field
Perpendicular to both the current and the magnetic field.
No of lines of force can pass through the unit area of magnetic field
yes
Lines of Force
No. They are are of different nature.
Magnetic lines do not cross each other. it is natural phenomenon.AnswerMagnetic 'lines of force' do not actually exist. They simply represent a 'model' which is used to explain the behaviour of a magnetic field through the use of something we can easily understand. In this case, one of the conditions for this model to apply is that these imaginary lines of force cannot intersect.The lines do not cross because the field can not have two values at one point. There is a basic equation that says that the lines always form closed loops:div B = 0, one of Maxwell's equations describing a property of the magnetic flux density B.
The magnetic force of a magnet is strongest at its poles. This is because the field lines of the magnetic field are most concentrated at the poles where they enter and leave the magnet. At the poles the magnetic field is strongest and the force is the greatest. The north pole is where the magnetic field lines enter the magnet. The south pole is where the magnetic field lines leave the magnet. The magnetic field lines are most concentrated at the poles. The magnetic force is greatest at the poles.
Yes. Magnetic lines of force penetrate paper with little to no difficulty.
No.
The closer the magnetic field lines, the stronger the magnetic force in that area.
magnetic lines of force
If magnetic lines are close, then the magnetic field has a lot of magnetic lines of force packed together. This translates into a large number of flux lines per unit of area through which they're passing. A large number of flux lines per unit area means a high field density. High flux density means the magnetic field is strong compared to a field where the flux lines are not as close together.
