Question

A wire of length \( L \) having Resistance \( R \) falls from a height \( h \) in Earth's horizontal magnetic field. What is the current through the wire?

• A. \( \frac{hB}{R} \)
• B. \( \frac{hB^2}{R} \)
• C. \( \frac{hB^2}{2R} \)
• D. \( \frac{hB}{2R} \)

Hint:

When dealing with induced emf in a falling wire in a magnetic field, remember to apply Faraday's law and use the appropriate motion equations for falling objects to determine the velocity.
