Question

Which of the following statement is not correct about the magnetic field?
(a) Magnetic field lines form a continuous closed curve.
(b) Magnetic field line do not interest each other.
(c) Direction of tangent at any point on the magnetic field line curve gives the direction of magnetic field at that point.
(d) Outside the magnet, magnetic field lines go from South to North pole of the magnet.

Answer 1

Outside the magnet, magnetic field lines go from south to north pole of the magnet is not the correct statement regarding magnetic field.

Explanation:

• The two magnetic field lines never intersect each other.
• The tangent drawn to the field lines then it will have two direction of magnetic field at the same point of intersection which is not possible, since magnetic field line have only one direction at a particular point.
• Magnetic field lines are continuous curves.
• It originate from north pole and terminate on south pole.  
• But inside the magnet it moves from south pole to north pole forming a closed loop.
• So, there is no any origination or termination point like electric field.
• Magnetic field are connecting the arrows gives continuous magnetic field lines.
• Small compasses used to test a magnetic field will not disturb it.
