What are the dimensions of mutual inductance ?

Explanation

To find the dimensions of mutual inductance (M), we start from the relationship between the induced electromotive force (EMF) in a secondary coil and the rate of change of current in the primary coil.

### Step-by-Step Solution:

1. **Understand the relationship**: The induced EMF (E₂) in the secondary coil is proportional to the rate of change of current (di₁/dt) in the primary coil. This can be expressed as:
\[ E₂ = M \cdot \frac{di₁}{dt} \]
