Question

A rectangular loop with L_1=0.15m and L_2 = 0.35 m is sitting in a magnetic field B = 0.15 T as shown in the figure. There is a counterclockwise current I = 0.85 A in the loop Randomized Variables L_1 = 0.15m L_2 = 0.35m B = 0.15 T I = 0.85 A Express the magnitude of the magnetic force on ab or cd, F_1 in terms of the length L_1, current I and magnetic field B. Part (b) Calculate the numerical value of the magnitude of the force, F_1 on ab or cd in N Part (c) Express the magnitude of the magnetic force on nc or ad, F_2 in terms of the length L_2, Current I and magnetic field B Part (d) Which direction does the force on ab act?

Explanation / Answer

Here ,

L1 = 0.15 m

L2 = 0.35 m

B = 0.15 T

I = 0.85 A

part A)

F1 = B*I*L1

the magnitude of force F1 is B*I*L1

part B)

F1 = B*I*L1

F1 = 0.15 * 0.15 * 0.85

F1 = 0.0191 N

the value of F1 is 0.0191 N

part C)

for the force F2

theta = 0

F2 = B*I* L2 * sin(theta)

F2 = B*I* L2 * sin(0)

F2 = 0 N

part D)

as the magnetic force , F = IL X B

using right hand rule

the direction of force is out of the page
