Question
Describe Ampere-Maxwell law in brief.
✓
Answer
According to Ampere-Maxwell law, magnetic field is generated by moving charges and also by varying electric fields. $\int \overrightarrow{ B } \cdot \overrightarrow{ d l}=\mu_0 I +\varepsilon_0 \mu_0 \frac{ d \phi_{ E }}{ dt }$ where, p0 and e0 are the permeability and permittivity of vacuum respectively and the integral is over a closed loop, I is the current flowing through the loop, E is the electric flux linked with the circuit.
