Magnetic field lines are continuous. The lines outside the magnet go from north to south, while inside goes from south to north creating a closed loop. This is because there are no magnetic monopoles.
no they are not
The copper by itself will do nothing of the sort. It will be surrounded by magnetic field lines if a current flows through it. It is the current that produces the magnetic field lines.
Never
Different latitudes of the sun rotate at different speeds. This tends to twist and bend the magnetic field lines.
no
-- Form a continuous circuit out of a conducting material. -- Move the conductor through the magnetic field, at an angle to the magnetic 'lines of force'.
Then, at some point, the field would go into two directions simultaneously, which doesn't make much sense. The magnetic field lines form continuous closed loops.The tangent to the field line at a point represent the direction of the net magnetic field B,at that point.The magnetic field lines do not intersect,if they did, the direction of the magnetic field would not be unique at the point of intersection.
They are called the magnetic field lines.
Magnetic field lines don't cross.
Lines of Force
Magnetic field lines are not a real observable thing, they are a tool used in physics to picture magnetic fields. A magnetic field is a continuous entity; it has no discrete force lines.
They are called the magnetic field lines.
straight parallel lines
The magnetic field lines are arranged circularly around the wire.
The closer the lines the stronger the magnetic field.
Magnetic field is made up of magnetic lines.
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.
