Question

Good Afternoon! Please answer this question..✏️

For a current in a long straight solenoid N-pole and S-pole are created
at the two ends.

Among the following statements, the incorrect
statement is:- (Why is it incorrect?)

(a) The field lines inside the solenoid are in the form of straight lines
which indicates that the magnetic field is the same at all points
inside the solenoid.
(b) The strong magnetic field produced inside the solenoid can be used
to magnetise a piece of magnetic material like soft iron, when
placed inside the coil.
(c) The pattern of the magnetic field associated with the solenoid
is different from the pattern of the magnetic field around a bar
magnet.
(d) The N-pole and S-pole exchange positions when the direction of
current through the solenoid is reversed.​

Answer 1
