Question

which of the following units belongs to magnetic flux

a. Amper volt
b. Tesla
c. Volt / s
d. Tesla m
e. C. Ω

Answer 1

Magnetic flux is defined as no of magnetic field lines through a surface.

Magnetic flux=Magnetic*area

unit of magnetic flux = unit of magnetic field * unit of area

$\begin{align*} &=\left (\text{unit of }\frac{Force}{current * length} \right )* m^{2}\\ &=\frac{N}{A*m}*m^{2}\\ &=\frac{N*m}{A}\\ &=\frac{N*m*s}{C}\text{ [since, ampere = C/s]}\\ &=V.s \text{ [since volt = J/C = Nm/C]} \end{align*}$

Therefore, Unit of magnetic flux in terms of

a) tesla is $T.m^{2}$

b) volt is $\text{V.s or volt.s}$

c) joule is $\frac{J}{A} \text{ [where A = ampere}]$

so, none of the options is matching.
