A circular loop of radius 11.7 cm is placed in a uniform magnetic field. (a) If the field is directed perpendicular to the plane
Mama L [17]

Answer:

Magnetic field, B = 0.199 T

Explanation:

It is given that,

Radius of circular loop, r = 11.7 cm = 0.117 m

Magnetic flux through the loop, \phi=8.6\times 10^{-3}\ T/m^2

The magnetic flux linked through the loop is :

\phi=B.A

\phi=BA\ cos\theta

Here, \theta=0

B=\dfrac{\phi}{A}

or

B=\dfrac{\phi}{\pi r^2}

B=\dfrac{8.6\times 10^{-3}}{\pi (0.117 )^2}

B = 0.199 T

So, the strength of the magnetic field is 0.199 T. Hence, this is the required solution.

Describe electronegativity, and explain the trend of electronegativity in the Periodic Table
vaieri [72.5K]

Explanation:

Electronegativity is the property of an atom that attracts the shared pair of an electron to itself. There is a trend in the periodic table.

While moving down in a group, the electronegativity decreases. This is due to the reason that as we move down the number of shells added and so the electron become very far from the pull of the nucleus.

As we move across a period the electronegativity increases. This is because of the no. of charge on the nucleus increase.
