Question

What is the SI unit of Magnetic Induction?

• A. Weber
• B. Tesla (T)
• C. Henry
• D. Ampere

Hint:

Magnetic field strength \(B\) is measured in Tesla (T). \(1\,T = 1\,\text{Weber}/m^2\).

Answer 1

The Correct Option is B

Step 1: Understanding the Question:
The question asks for the standard International System of Units (SI) unit used to measure magnetic induction (also called magnetic flux density).
Step 2: Key Formula or Approach:
Magnetic Induction (\( B \)) is defined by the force on a moving charge: \( F = q(v \times B) \).
Units: \( B = \frac{F}{qv} \rightarrow \frac{N}{C \cdot m/s} = \frac{N}{A \cdot m} \).
Step 3: Detailed Explanation:
The derived SI unit for magnetic induction is the Tesla (T).
One Tesla is equal to one Weber per square meter (\( Wb/m^2 \)).
- Weber is the unit of magnetic flux.
- Henry is the unit of inductance.
- Ampere is the unit of electric current.
Step 4: Final Answer:
The SI unit of Magnetic Induction is Tesla (T).
