# Derive Maxwell’s two general equations in integral and differential form. - Applied Physics 2

Short Note

Derive Maxwell’s two general equations in integral and differential form.

#### Solution

1. As the magnetic lines of forces are closed, the number of magnetic lines of flux entering any surface is exactly same as leaving.

 ∴ Φ_v bar(B) . ds = 0

 Using Gauses divergence theorem , convert surface integral to volume integral .

∴ Φ_V bar(B) . ds =  Φ_V   V . bar(B) dV = 0

∴ V . bar(B) = 0 

This is point form of Maxwell's second equation .

Maxwell’s second equation in integral form

∴ Φ_v bar(B) . ds = 0 `
