YES!
The direction of magnetic field lines are from north to south
You can reverse the direction of the magnetic field by reversing the direction of the electrical current.
No. It has. Since transverse electric mode has it's wave propagating in the Z direction, and has magnetic field existing in the same direction with NO electric field... Likewise, transverse magnetic mode has it's wave propagating in the Z direction and has electric field existing in the same direction with NO magnetic field.
perpendicular to the magnetic field direction
Different latitudes of the sun rotate at different speeds. This tends to twist and bend the magnetic field lines.
Direction of the magnetic lines too would get changed
Direction of the magnetic lines too would get changed
It is a bearing (a direction) based on a magnetic compass reading.
Earth has magnetic properties
Fleming's right hand rule is used to determine the direction of the magnetic force on a current-carrying conductor in a magnetic field. By aligning the thumb with the direction of current flow, the forefinger with the direction of the magnetic field, the middle finger points in the direction of the magnetic force acting on the conductor.
The magnetic field collapses to zero, then builds up again for the current in the opposite direction.
The angle between the direction your compass points and the direction you're facing is the 'magnetic azimuth'. The angle between the direction to the north pole and the direction you're facing is the 'true azimuth'. They are virtually never the same angle. The difference between them is the 'magnetic declination' or the 'compass declination' in the place where you are at in which.
