I have to calculate B(magnetic field) from Faraday's Law.?

Question

My Guide wants me to get answer in terms of
Ampere per Metre. The units I m getting are :

Volt * Second/metre^2.

Kindly give suitable reason.

Answer 1

Volt is not a base unit whereas ampere and metre are.
volt = joule/coulomb = kg m² / s² A s = kg m² / A s³

The unit of B is not ampere per metre: it is Newton per metre ampere from F = B I l. You are calculating B from Faraday's law and the definition of flux: Φ = B A. By converting everything into base units {kg m s A} you should be able to show that the two units are in fact the same.

Answer 2

ampere/meter is the unit of H, magnetic field intensity. B is the magnetic flux usually given in teslas (weber/m^2). The relationship is B=µH, where µ = magnetic permeability. The derived units of a tesla are volt*second/meter^2. In order to get the answer you want, you have to divide by µ.
