Tutorial_02_01: Simple simulation
In this tutorial, we create a simple simulation of a coil falling under gravity and bouncing off of a floor. For the coil we use a ring of current. The ring of current has zero current and there are no other electromagnetic objects to interact with, so there are no electromagnetic interactions in this simulation. The collision with the floor is perfectly elastic, and there is no friction in the model, so the motion repeats indefinitely.
Tutorial_02_02: Simple simulation with a graph and a damping slider
In this tutorial, we create a simulation of a coil falling under gravity and bouncing off of a floor. We also create a graph of the vertical position of the coil as a function of time. In addition, we add a slider that allows us to vary the amount of damping in the world. By setting the slider to a non-zero value, the user can get the height of the coil to decay exponentially. The user can set the amount of damping either by moving the slider or by entering a value in the box to the right of the slider AND HITTING ENTER.
Tutorial_02_03: 3D Objects, Native and Imported
In this tutorial, we create two native 3D objects (a green sphere and a flat red cylinder--i.e. a disk). We also import two .3DS objects (a black tapered cone and an orange hemisphere), and import one .obj object (a box covered with tinfoil). The vertical positions of the two native 3D objects are controlled by sliders.
Tutorial_02_04: Two Interacting Electromagnetic Objects
In this tutorial, we create two electromagnetic objects which interact, a ring of current which is free to move along the vertical axis, and a magnetic dipole which is fixed in space. Gravity is downward. We can vary the amount of current in the ring to change the height of the ring of current above the dipole. We also have a <i>wall</i> at the same position as the magnetic dipole. The ring of current rests on this wall if there is no current in the ring or if the current in the ring is such that the ring cannot levitate above the dipole.
Tutorial_02_05: Vector Field Grid
In this tutorial, we add a vector field grid to show the fields in Tutorial_02_04.
Tutorial_02_06: Field Lines
In this tutorial, we add a set of field lines to show the fields in Tutorial_02_04.
Tutorial_02_07: Line Integral Convolution
In this tutorial, we add a field line convolution to show the fields in Tutorial_02_04.
Tutorial_02_08: All of the Above
In this tutorial, we include elements of all of the tutorials 02_01 through 02_07.
