Question

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

Answer 1

Hint: Magnetic induction is a phenomenon of inducing a magnetic field in between of a coil due to a varying magnetic flux passing through the coil. It is equivalent to a magnetic field. Hence, its unit is the same as the unit of magnetic field.

Complete answer:
Let us understand what is meant by magnetic induction. Magnetic induction is a phenomenon of inducing a magnetic field in between of a coil due to a varying magnetic flux passing through the coil. We can also say that a current carrying coil induces a magnetic field in the other coil (having no current initially) placed nearby. This produced magnetic field is simply called magnetic induction.We know that the SI unit of the magnetic field is tesla. Hence, tesla is a unit of magnetic induction.

Hence, the correct option is B.

Note: Magnetic flux is defined as the product of magnetic field and the area perpendicular to it. The SI unit of magnetic flux is Weber (Wb).Magnetic intensity is defined as the magnetic force applied on the unit monopole of a bar magnetic. Magnetic field intensity is denoted by H. This quantity can be co-related to electric field intensity from the concept of electrostatics. The unit of magnetic intensity is $A{{m}^{-1}}$.Magnetic moment is a property of a magnetic dipole. Its magnitude is equal to the product of the pole strength and the distance between the poles of the dipole. Its unit is $A{{m}^{2}}$.
