What are the two ways in which you can trace the magnetic field pattern of a bar magnet?
Draw a diagram to show the magnetic field lines around a bar magnet.
The magnetic field lines:
(a) intersect at right angles to one another
(b) interest at an angle 45° to each another
(c) do not cross one another
(d) cross at an angle of 60° to one anotherv
The strength of the magnetic field between the poles of an electromagnet would be unchanged if:
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.
Indicate by crosses, the likely positions of the neutral points.
In a uniform magnetic field, the field lines are:
State briefly the molecular theory of magnetism.
State the inference drawn about the direction of the magnetic field lines on the basis of the following diagrams.

| Figure 'a' | Figure '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.
