What is the main reason for using a solenoid instead of a straight wire to produce magnetic field?

Open in App

Solution

Solenoid is used more than straight wire as induced magnetic field is more as with increase in number of turns the field lines intersect the circuit multiple times.

Q. Question 4
For a current in a long straight solenoid N- and S-poles are created at the two ends. Among the following statements, the incorrect statement is

(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- and S-poles exchange position when the direction of current through the solenoid is reversed
