MCQ
Which law can ampere’s circuital be derived from?
- AGauss Law
- BNewton’s Law
- CKirchhoff’s Law
- ✓Biot$-$Savart Law
✓
Answer
Correct option: D.
Biot$-$Savart Law
In classical electrodynamics, the magnetic field given by a current loop and the electric field caused by the corresponding dipoles in sheets are very similar, as far as we are far away from the loop, which enables us to deduce Ampere’s magnetic circuital law from the Biot$-$Savart law easily.
