Question
A wire with current of 4 A and length of 80 meter is positioned on a horizontal table with a rectangular top of dimensions 3 m by 4 m. The wire lies straight between the opposite ends of a diagonal of the rectangle. How much is the magnetic force in Newtons on this segment of wire if a vertical magnetic field of 1.5 T exists?

How much is the magnetic force in Newtons on this segment of wire if a vertical magnetic field of 1.5 T exists?Explanation / Answer
Force = i*l*B = 4*l*1.5 here l= root of (3^2+4^2) =5
Hence force F= 4*5*1.5 = 30 N
