A long solenoid of radius $1 mm$ has $100 turns$ per $mm$ . If $1 A$ current flows in the solenoid, the magnetic field strength at the centre of the solenoid is:NEET 2022 (Phase 1)

Options:

Answer:

Solution:

Radius $= 1 mm$

$N = 100 turns$ per $mm$

Current $= 1 A$

Magnetic field strength at the centre of the solenoid is,

$B = μ_{0} n i = 4 π \times 10^{- 7} \times 100 \times 10^{3} \times 1 \Rightarrow B = 12.56 \times 10^{- 2} T$
