A glass rod of length l moves with velocity v in a uniform magnetic field B. What is the e.m.f induced in the rod?

Explanation

To solve the problem of finding the induced electromotive force (e.m.f) in a glass rod of length \( l \) moving with velocity \( v \) in a uniform magnetic field \( B \), we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Setup**:
- We have a glass rod of length \( l \) moving with a velocity \( v \) in a magnetic field \( B \). The direction of the magnetic field is perpendicular to the direction of the rod's motion.

2. **Identify the Nature of the Rod**:
