A copper sheet with length 1.0 m, width 0.50 m, and thickness 1.0 mm is oriented so that its largest surface area is perpendicular to a magnetic field of strength 6.4 T. The sheet carries a current of 3.5 A across its length. What is the magnitude of the force on this sheet?what is the formula that involves Area when finding the Fb??can someone tell me?
