1) In the case of a bar magnet, outside it, the magnetic lines of forces start from North Pole and end on South Pole. But inside it, the lines of force start from south and end on North Pole. According to definition of direction of lines of force, it is the direction in which a unit north pole would move when placed in a magnetic field. This is true outside the bar magnet but not so inside it.
The direction of the magnetic field is perpendicular to the wire and is in the direction the fingers of your right hand would curl if you wrapped them around the wire with your thumb in the direction of the current.he magnetic field of an infinitely long straight wire can be obtained by applying Ampere's law. Ampere's law takes the form. and for a circular path centered on the wire, the magnetic field is everywhere parallel to the path.
