Question

For a current in a long solenoid N and S poles are created at the two ends. Among the following

statement, the incorrect statement is

(a) The magnetic field lines the solenoids are in the form of straight lines which indicate that the

magnetic field is same at all points in the solenoid

(b) The strong magnetic field produced inside the solenoid can be use to magnetise a piece of

magnetic material, when soft iron is placed inside the coil

(c) The pattern of magnetic field associated with the solenoid is different from the pattern of the

magnetic field around a bar magnet.

(d) The N and S poles exchange position when the direction of current through the solenoid is

reversed.

​

Answer 1

Answer:

option C is wrong

solenoid and bar magnets have similar magnetic fields

Answer 2

Answer:

Hey Friend!!

Option (C) is incorrect because The pattern of magnetic field associated with the solenoid is SAME as the pattern of magnetic field in a bar magnet.
