Question

Name the physical quantity having unit J/T.

Answer 1

The physical quantity is MAGNETIC MOMENT.

• 'J' means Joules and 'T' means Tesla.

• Now, J/T refers to the SI unit of Magnetic Moment.

• Let magnetic moment be M :

$M = \dfrac{torque}{field \: intensity}$

• Putting SI units

$\implies | M | = \dfrac{Nm}{T}$

• 'Nm' can be written as Joules (J).

$\implies | M | = \dfrac{J}{T}$

So, J/T represents unit of Magnetic Moment.

Answer 2

The physical quantity is MAGNETIC MOMENT.

• 'J' means Joules and 'T' means Tesla.
• Now, J/T refers to the SI unit of Magnetic Moment.
• Let magnetic moment be M :

$m = \frac{torque}{field \: intensity}$

• Putting SI units

$= > |M| = \frac{Nm}{ T}$

• 'Nm' can be written as Joules (J).

$|m| = \frac{j}{t}$

So, J/T represents unit of Magnetic Moment.
