An aluminium rod of length 8.0 cm is moved through a magnetic field perpendicular to the rod, resulting in a potential difference of 0.040 V across the rod. Determine the strength and direction (inward or outward of the page) of the magnetic field in this scenario.

• A. 0.167 T, outward of the page
• B. 0.167 T, inward of the page
• C. 1.50 T, inward of the page
• D. 1.50 T, outward of the page

Answer: (B)
