Question

The magnetic induction field has the dimensions of

• A. Force
• B. Force constant
• C. Surface tension
• D. $\frac{\text{Surface tension}}{\text{Current}}$

Answer 1

Answer: (D)

$\frac{\text{Surface tension}}{\text{Current}}$

Answer 2

$\because F=q v B$
$\therefore B=\frac{F}{q v}=\frac{F}{q\left(\frac{d}{t}\right)}=\frac{F}{I d}=\frac{T}{I}$
$\therefore B=\frac{\text { Surfacc tension }}{\text { Current}}$
