Question

Which expression is Gauss's Law for Magnetism?

Options

• \[\Phi_B=\int\vec B\cdot d\vec A\]

• \[\varepsilon=-N\frac{d\Phi_B}{dt}\]

• \[\oint\vec B\cdot d\vec A=0\]

• \[\Phi=NBA\cos\theta\]

Answer 1

Expression of Gauss's Law for Magnetism: \[\oint\vec B\cdot d\vec A=0\]

Gauss's Law for Magnetism states that net magnetic flux through a closed surface is zero. The closed-surface integral expresses this result.
