Magnetic field inside the solenoid along its axis _______?

اس کے محور کے ساتھ سولینائڈ کے اندر مقناطیسی فیلڈ _______؟

Infinite line

Non-uniform

Strong and uniform

None of these

Inside a solenoid, the magnetic field is strong and uniform along its axis.

Due to the superposition of magnetic fields from multiple coils.

This field is given by B = μ₀nI, where n is the number of turns per unit length and I is the current.
