*** I know the correct answer is included right under the question but I really needed to see the process/steps I need to take in order to get that answer please! ***

9-Moving rod in a B field. A rod ab moves in a 0.20 Tesla B field (x) with a velocity v= 3.5 m/s which is inclined 55° with respect to its length Lab 0.40 m. Calculate the induced voltage V,b 55° with respect to its length Lab 0.40 m. Calculate the induced voltage Vab and tell what end of the rod is at the higher potential, a or b Ans 0.23 volt a or b? ×L× × ×

Explanation / Answer

relation between magnetic field and velocity and length and induced voltage is

the induced voltage = BL V sin (theta )

= 0.20 *0.40 *3.5 sin (55 )

= 0.23 volt

point ( a ) have higher potential
