A current of 17.0 mA is maintained in a single circular loop of 2.00 \mathrm{~m} circumference. A magnetic field of 0.800T is di
poizon [28]

The magnetic moment is -

M = 5.5 x 10^{-3} Am^{2}.

We have current carrying single circular loop placed in a magnetic field

parallel to the plane of the loop.

We have to determine the Magnetic moment of the loop.

<h3>What is the formula to calculate the magnetic moment of loop?</h3>

The formula to calculate the magnetic moment of the loop is -

M = NIA

where -

N -  Number of turns

I - Current in the loop

A - Area of the loop

According to the question, we have -

I = 17mA = 0.017A

Circumference (C) = 2 meters

B = 0.8 T

Now -

C = 2

2\pir = 2

\pir = 1

r = \frac{1}{\pi }

r = 0.32

Using the formula -

M = NIA

M = \piNIr^{2}

M = 3.14 x 1 x 0.017 x 0.32 x 0.32

M = 3.14 x 4 x 0.017

M = 5.5 x 10^{-3} Am^{2}

Hence, the magnetic moment is -

M = 5.5 x 10^{-3} Am^{2}

The density of this material is 2 g/cm3 there are 24 cm3 find the total mass
Fynjy0 [20]

Answer:

<h2>The answer is 48 g</h2>

Explanation:

The mass of a substance when given the density and volume can be found by using the formula

mass = Density × volume

From the question we have

mass = 2 × 24

We have the final answer as

<h3>48 g</h3>

Hope this helps you
