Question
cm segment of this wire. Show the direction of the force m a diagram. 2. A wire carries a steady current of 2.40 A. A straight section of the wire is 0.750 m long and lies along the x axis within a uniform magnetic field of 1.60 T in the positive z direction. If the current in the wire is in the positive x direction, what is the magnitude and direction of the magnetic force on the section of the wire? 3. The bent wire shown in the figure below lies in a uniform magnetic field. Each straight section is 2.0 m long and makes an angle of 60 degree with the x-axis, and carries a current of 2.0 A. What is the net magnetic force on the wire in unit-vector notation if the magnetic field B is given by: 4.0 k T and 4.0 I TExplanation / Answer
2)
wire carries steady state current=2.4A
length of wire=0.75m
B=1.6T
whenever current carrying conductor is placed inside the magneticfield.it experiences the force
F=I.(LXB)
=2.4*0.75axx1.6az
=-2.88ay
MAGNITUDE=2.88N
direction of force is negative y direction
3)
a)
F=ILBsin(theta)
=2*2ax*4az*sin(60)
=-13.856ay
MAGNITUDE=13.856N
IN NEGATIVE Y DIRECTION
b)
B=4i
in this case magneticfield is parllel to length of wire
so F=0
