== What You Will Learn ==
Previously, you observed that the electric field in the region between the two parallel plates of a capacitor is fairly uniform. In this tutorial you will use parallel metal plates held at different potentials to generate a uniform electric field. Then you will simulate the interaction of this uniform field with immersed objects of different material compositions.

The figures below are the plots of the data files "Sensor_3_X_ETotal.DAT" and "Sensor_3_Z_ETotal.DAT" in EM.Gridthe. These show the variation of the electric field along the X and Z axes, respectively.

To draw a ellipsoid, click the '''Ellipsoid ''' [[Image:ellipsoidiconx.png]] button from the Object Toolbar or select the menu item <b>Object → Solid → Ellipsoid </b>.

After drawing the PEC ellipsoid and placing it at the center of the gap region between the two metal plates, your physical structure should look like this:

Instead of deleting the PEC ellipsoid and drawing a new dielectric ellipsoid, you can simply move the object "Immerse" from teh the group "PEC_3" to the group "Dielectric_1". Follow the same procedure as you did in Tutorial Lesson 1 using the '''Move To''' items in the contextual menu of the spheroid object.
