The SI unit of magnetic field is ____

Options

A. Tesla
B. VA
C. Wm
D. Wh

Explanation

To find the SI unit of magnetic field, we can follow these steps:

### Step 1: Understand the Concept
The magnetic field is a vector field that describes the magnetic influence on moving electric charges, electric currents, and magnetic materials.

### Step 2: Identify the Options
The options provided are:
1. Tesla
2. Volt into ampere
3. Weber meter
4. VotR

### Step 3: Recall the Definition
The SI unit of magnetic field is defined based on the force experienced by a charge moving through the field.

### Step 4: Determine the Correct Unit
Among the options:
- **Tesla (T)** is the standard unit of magnetic field strength in the International System of Units (SI).
- **Volt into ampere** is a unit of power (Watt).
- **Weber meter** is not a standard unit for magnetic field; Weber (Wb) is the unit of magnetic flux.
- **VotR** does not correspond to any recognized unit.

### Step 5: Conclusion
The correct answer is **Tesla (T)**.

Thus, the SI unit of magnetic field is **Tesla**.
