A straight segment of a current-carrying wire has a current element IL where I = 2.70 A and L = 3.20 cm i + 4.30 cm j. The segment is in a region with a uniform magnetic field given by 1.24 T i. Find the force on the segment of wire. (Give the x, y, and z components.)

The component of the force in negative z-direction is -0.144 N.

The given parameters;

  • current in the wire, I = 2.7 A
  • length of the wire, L = (3.2 i + 4.3j) cm
  • magnetic filed, B = 1.24 i

The force on the segment of the wire is calculated as follows;

[tex]F = ILBsin(\theta)[/tex]

where;

  • θ is the angle wire and magnetic field

The force on the wire segment will be perpendicular in negative z-direction (applying right hand rule), so there won't be any x and y component of the force.

The angle between the wire and the magnetic field is calculated as follows;

[tex]\theta = tan^{-1} (\frac{y}{x} )\\\\\theta = tan^{-1} (\frac{4.3}{3.2} )\\\\\theta = 53.3 \ ^0[/tex]

The magnitude of the wire length is calculated as follows;

[tex]|l | = \sqrt{3.2^2 + 4.3^2} = 5.36 \ cm = 0.0536 \ m[/tex]

The component of the force in negative z-direction is calculated as;

[tex]F_z = -ILB sin(\theta)\\\\F_z = -2.7 \times 0.0536 \times 1.24 \times sin(53.3)\\\\F_z = -0.144 \ N[/tex]

Thus, the component of the force in negative z-direction is -0.144 N.
