Question

A wire of length \( 1 \, \text{m} \) moving with velocity \( 8 \, \text{m/s} \) at right angles to a magnetic field of \( 2 \, \text{T} \). The magnitude of induced emf between the ends of the wire will be:

• A. \( 20 \, \text{V} \)
• B. \( 8 \, \text{V} \)
• C. \( 12 \, \text{V} \)
• D. \( 16 \, \text{V} \)

Hint:

The induced emf in a conductor moving perpendicular to a magnetic field depends on the product of the magnetic field strength, the velocity of the conductor, and its length. Ensure all units are consistent when performing calculations.
