A rectangular loop of wire measures 1.0 m by 1.0 cm. If a 7.0-A current flows through the wire, what is the magnitude of the magnetic force on the centermost 1.0-cm segment of the 1.0-m side of the loop?

Fm = ILBsin of angle

Fm = Magnetic force

I= Electric current

L= Length of conductor

B= magnetic field intensity

B= (4∏x10^-7)(7.0A)/(2∏)(0.01m) = 1.4x10^-8

Fm= (7.0A)(1.0m)(1.4x10^-8)= 9.8x10_8
