However, the bead does not move in the direction of the magnetic field. It is constrained to move along the slinky. The work is calculated from the component of the force in the direction of movement. For example, when the movement is 90 degrees from line integrals of vector fields direction of the force, the magnetic field does no work.

First, what is the direction of movement? It is shown by the blue vector in the below figure.

Applet loading Particle on helix with magnet and tangent vector. In this section we are going to evaluate line integrals of vector fields. That really is a dot product of the vector field and the differential really is a line integrals of vector fields.

What if we traverse C in the clockwise direction? Let -C denote the line integral on C in the clockwise direction.

Line integrals and vector fields

A plot of the vector field and the curve is shown above. Dependence of Work on the Path In general, the amount of work required to move the object from 2,0 to -2,0 depends on the path taken!

Suppose line integrals of vector fields we move the object in the above vector field on the real axis instead of on the ellipse.

The line integral is No work is required! Let's define a vector field.

Line Integrals of Vector Fields

So let's say that I have a vector line integrals of vector fields f, and we're going to think about what this means in a second. It's a function of x and y, and it's equal to some scalar function of x and y times the i-unit vector, or the horizontal unit vector, plus some other function, scalar function of x and y, times the vertical unit vector.

So what would something like this be? This is a vector field. This is a vector field in 2-dimensional space.

We're on the x-y plane. Or you could even say, on R2. Either way, I don't want to get too much into the mathiness of it. But what does this do? Line integrals of vector fields, if I were to draw my x-y plane, so that is my, again, having trouble drawing a straight line.

All right, there we go. That's my y-axis, and that's my x-axis. I'm just drawing the first quadrant, and but you could go negative in either direction, if you like.
