MHT CET 2025 Physics question
The magnetic field intensity H at the centre of a long solenoid having n turns per unit length and carrying a current I, when no material is kept in it is ( = permeability of free space)
Answer: (C)
Solution
Inside a long solenoid the magnetic induction is . Magnetic field intensity is defined as (in vacuum, no material), so , option
