A rectangular 10.0 cm by 18.0 cm circuit carrying an 8.00 A current is oriented

Question

A rectangular 10.0 cm by 18.0 cm circuit carrying an 8.00 A current is oriented with its plane parallel to a uniform 0.800 T magnetic field.

A.) Find the magnitude of the magnetic force on the ab segment  of this circuit. Express your answer in newtons to two significant figures. Fab = _____ N

B.) Find the magnitude of the magnetic force on the bc segment of this circuit. Express your answer in newtons to two significant figures. Fbc = _____ N

C.) Find the magnitude of the magnetic force on the cd segment of this circuit. Express your answer in newtons to two significant figures. Fcd = _____ N

D.) Find the magnitude of the magnetic force on the da segment of this circuit. Express your answer in newtons to two significant figures.  Fda= _____ N

Explanation / Answer

Solution-

By using the formula F = BILsin for each segment

A)For ab, F = (.80)(8)(.18)(sin 90) = 1.152 N

b)For bc, F = (.80)(8)(.1)(sin 0) = 0 N

c)For cd, F = (.80)(8)(.18)(sin 90) = 1.152 N

d)For da, F = (.80)(8)(.1)(sin 0) = 0 N
