A glass rod of length "L" moves with velocity "V perpendicular to a uniform magnetic field "B", the emf induced in rod is:
Correct answer: C. Zero
- A. vBLsin0
- B. vBL
- C. Zero
- D. NωABsinθ
Explanation
As glass is an insulator. So, there no free charges in the glass rod to produce an induce emf.

About Electromagnetism
Magnetic flux density and magnetic flux describe the strength of a magnetic field and the field passing through a surface. A charged particle moving through a magnetic field experiences a force perpendicular to its velocity and may follow circular or helical motion, depending on the angle between velocity and field.
