The unit of magnetic flux is

Options

A. Tesla
B. Gauss
C. Webar
D. `"Webar"//m^(2)`

Answer

To determine the unit of magnetic flux, we can follow these steps:

### Step 1: Understand the Definition of Magnetic Flux
Magnetic flux (Φ) is defined as the product of the magnetic field (B) and the area (A) through which the field lines pass. Mathematically, it is expressed as:
\[ \Phi = B \cdot A \]

### Step 2: Identify the Units of Magnetic Field and Area
- The unit of magnetic field (B) is Tesla (T).
- The unit of area (A) is square meters (m²).

### Step 3: Combine the Units
Using the formula for magnetic flux:
\[ \Phi = B \cdot A \]
Substituting the units:
\[ \Phi = \text{Tesla} \cdot \text{m}^2 \]

### Step 4: Convert Tesla to Weber
We know that:
1 Tesla (T) = 1 Weber per square meter (Wb/m²). Therefore:
\[ \Phi = (1 \, \text{Wb/m}^2) \cdot \text{m}^2 \]
This simplifies to:
\[ \Phi = 1 \, \text{Wb} \]

### Step 5: Conclusion
Thus, the unit of magnetic flux is Weber (Wb).

### Final Answer
The unit of magnetic flux is **Weber (Wb)**.
