14. -/5.5 points CJ10 21.P037 My Notes Ask Your A loop of wire has the shape of a right triangle (see the drawing) and carries a current of I = 5.60 A. A uniform magnetic field is directed parallel to side AB and has a magnitude of 1.60 T 55.0 2.00 m (a) Find the magnitude and direction of the magnetic force exerted on each side of the triangle. side AC N directed N directed Select- N directed Select… side CB ( -D side BA ( Select (b) Determine the magnitude of the net force exerted on the triangle. Additional Materials Section 21.5

Explanation / Answer

A)

Side AC

Magnetic force= ILB= 5.6*2*tan(55°)*1.6 = 25.6 N

Direction= inside page

B)

Side CB

Magnetic force=5.6*cos(35°)*(2/cos(55°))*1.6=5.6*0.819*(2/0.5736)*1.6= 25.6 N

Direction=

Outside page

C)

Side BA

Magnetic forece = 0 .

D) forces are opposite direction

Net force = 25.6-25.6 =0 N
