Question

Answer the following question:Be sure to show all work. Include formulae and units.Be sure to include relavant, meaningful diagram and a complete circuit diagram with circuit related problem. take enough space, don't try to squeeze everything on a small space!(problems are from:principle of physics:calculus based; Chapter: Magnetic forces and Magnetic field)

4.) A long straight wire carrying a current of 20 A.A rectangular loop of wire carries a clockwise current of 15 A.The dimensions of the loop are 0.2 m X 0.01 m, with the loop

Answer #1

**I assume reactangular loop is right to the straight
wire.**

**let, l = 0.2 m**

**bredth, b = 0.1 m**

**distance between loop and wire, a = 0.05 m**

**magnetic force on the left segment, FL =
mue*I1*I2*l/(2*pi*a)**

**= 4*pi*10^-7*20*15*0.2/(2*pi*0.05)**

**= 2.4*10^-4 N (towards left)**

**magnetic force on the right segment, FR =
mue*I1*I2*l/(2*pi*(a+b))**

**= 4*pi*10^-7*20*15*0.2/(2*pi*(0.05+0.1))**

**= 8*10^-5 N (towards right)**

**magnetic force on upper and lower segments are equal in
magnitude and acts opposite direction.**

**so,**

**Fnet = FL - FR**

**= 2.4*10^-4 - 8*10^-5**

**= 1.6*10^-4 N**

**direction : towards left (towards straight
wire)**

Two long, parallel conductors separated by 14.0 cm carry
currents in the same direction. The first wire carries a current
I1 = 5.50 A, and the second carries
I2 = 8.00 A. (Assume the conductors lie in the
plane of the page.)
(a) What is the magnitude of the magnetic field created by
I1 at the location of
I2?
T
(b) What is the force per unit length exerted by
I1 on I2?
magnitude
N/m
direction
---Select--- towards wire 1...
