Question

Match the following

Physical Quantity	Unit
a) Magnetic Moment	e) $Amp-m$
b) Magnetic Flux Density	f) $Amp/m$
c) Intensity of Magnetic Field	g) $N-m^3/Wb$
d) Pole strength	h) $Gauss$

• A. a-e, b-f, c-g, d-h
• B. a-g, b-h, c-f, d-e
• C. a-g, b-f, c-h, d-e
• D. a-e, b-f, c-h, d-g

Answer 1

Answer: (B)

a-g, b-h, c-f, d-e

Magnetic moment=IA
$=A{L}^2$
$=\frac{N-m^3}{wb}$
Magnetic flux density=$\frac{Wb}{L^3}$
$=gauss$
Intensity of magnetic fileld=$\frac{B}{{\mu }_u}-m$
$=\frac{IA}{V}$
$=A{m}^{-1}$
Pole strength P=$\frac{m}{L}$
$=\frac{IA}{L}$
$=Am$
