The figure given below shows the magnetic field between two magnets:
Copy the diagram and label theother poles of the magnets.
Which is the weaker magnet?
उत्तर
Magnet 1 S-N and Magnet 2 N-S
Magnet 2 is weaker because its lines are bending more. In other words, its lines are experiencing more force exerted by Magnet 1.

Figure. shows a bar magnet placed on the table top with its north pole pointing towards south. The arrow shows the north-south direction. There are no other magnets or magnetic materials nearby.
Insert two magnetic field lines on either side of the magnet using arrow head to show the direction of each field line.
Select the correct option:
The magnetic strength of a bar magnet is:
State briefly the molecular theory of magnetism.
State whether true or false. If false, correct the statement.
Magnetic field lines always repel each other and do not intersect.
Name the poles P, Q, Rand S of the magnets in the following figures 'a' and 'b':

Assertion (A): Magnetic field lines never intersect each other.
Reason (R): If they intersect, then at the point of intersection, the compass needle would point towards two directions, which is not possible.
