Question:
The SI unit of Magnetic Induction is:
The SI unit of Magnetic Induction is:
Show Hint
Remember the relationship between units: \( 1 \text{ Tesla} = 1 \text{ Weber} / \text{m}^2 \).
Also, note the conversion factor for CGS units: \( 1 \text{ Tesla} = 10^4 \text{ Gauss} \).

The Correct Option is B
Solution and Explanation
Step 1: Understanding the Concept:
Magnetic induction, also known as magnetic flux density or magnetic field \( B \), represents the strength of a magnetic field.
It defines the force experienced by a moving charge or a current-carrying wire in the field.
Step 2: Key Formula or Approach:
The approach is to identify the standard International System of Units (SI) for various electromagnetic quantities.
We will evaluate each option against standard physical definitions.
Step 3: Detailed Explanation:
Let us analyze each given option systematically.
Option (A) is Weber (Wb), which is the SI unit for magnetic flux (\( \Phi \)).
Option (B) is Tesla (T), which is the internationally accepted SI unit for magnetic induction or magnetic flux density.
Option (C) is Henry (H), which is the SI unit for electrical inductance (\( L \)).
Option (D) is Gauss (G), which is indeed a unit of magnetic induction, but it belongs to the older CGS system, not the SI system.
Therefore, Tesla is the only correct SI unit among the choices.
Step 4: Final Answer:
