Question

Tesla is the unit of:
A) Magnetic flux
B) Magnetic intensity
C) Magnetic induction
D) Magnetic moment

Answer 1

Hint: One tesla (1 T) is defined as the field intensity generating one newton (N) of force per ampere (A) of current per meter of conductor, Tesla is 1 $\dfrac{{{\text{weber}}}}{{{{\text{m}}^{\text{2}}}}}$, which is a measurement of magnetic induction.

Complete answer:
The set of lines of force that travels from the north pole to the south pole of the magnet is called the magnetic flux, and is symbolized by the letter $\phi $. The number of lines of force in the magnetic field determines the value of the flux. The greater the number of lines of force, the greater the flux and the stronger the magnetic field.
Weber is a unit of magnetic flux (Wb). Each one is equal to 108lines. Weber is a very large unit Therefore, in most practical cases, a micro weber ${{\epsilon \times Wb}}$ is used. 1 micro weber equals 100 lines of magnetic flux.
The magnetic flux density is the amount of magnetic flux per unit area perpendicular to the magnetic field. Its symbol is B, and its SI unit is Tesla (T). One Tesla is equal to one Weber per meter square,
$\dfrac{{{\text{Wb}}}}{{{{\text{m}}^{\text{2}}}}}$
The following formula for magnetic density expresses the flux density:
$\Rightarrow B = \dfrac{\phi }{A}$
Where $\phi $ is the flux and A is the cross-sectional area
$\therefore $ Tesla is the SI unit of magnetic induction

Hence Option A is correct.

Note: Tesla, unit of magnetic induction or magnetic flux density in the metre–kilogram–second system (SI) of physical units. One tesla equals one weber per square metre corresponding to 104gauss. In practice, the tesla is a large unit, and is used primarily in industrial electromagnetics. When dealing with practical magnets of the sort encountered in consumer products, a smaller unit of flux density called the gauss (symbolized G) is often used. There are ten thousand gauss in one tesla (${\text{1T = 1}}{{\text{0}}^{\text{4}}}{\text{G}}$).
