Web10 nov. 2024 · Ans:- If magnetic field lines were entirely confined within the core of a straight solenoid, the magnetic flux through the cross-section at each end of it would have been nonzero. But the magnetic flux of field B through any closed surface, as per Gauss' law must always be zero. WebThe magnetic field produced by a circular coil carrying current I is Proportional to I. The S.I unit of magnetic field is Tesla . The magnitude of horizontal intensity of earth’s magnetic field is3.5x10⁻⁵ T . For better result while doing tangent galvanometer experiment, the deflection should be in between 30o-60o. The value of μ₀ is 4πx10⁻⁷ NA⁻². briauna johnson csun
