CBSE Class 10 Answered

does the strength of solenoid increase if we keep iron inside?
Asked by shamimakhan924 | 18 Feb, 2019, 05:47: PM
answered-by-expert Expert Answer
Yes, when current passes through a solenoid, it produces its own magnetic field inside and outside the solenoid.
When a soft iron bar/core is placed inside the solenoid, it magnetizes the iron bar thereby increasing the strength of the magnetic field inside the solenoid.

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