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 T

Explanation / 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
