A beam of protons moves parallel to the x-axis in the positive x-direction, as shown above, through a region of crossed electric and magnetic fields balanced for zero deflection of the beam. If the magnetic field is pointed in the positive y-direction, in what direction must the electric ...
(DC) electric power supply. It uses an electronic closed-loop controller to switch DC currents to the motor windings producing magnetic fields which effectively rotate in space and which the permanent magnet rotor follows. The controller adjusts the phase and amplitude of the DC current(brushes) ...
Step 4:Try using different types of material (paper, fabric, aluminum foil) to shield the wire from an electric field source. What material(s) works best? How does this compare with theAC magnetic field experiment? As with magnetic fields, there is controversy about whether or not stray ele...
Electric fields may be described as “invisible webs” of interaction across space between electrically charged objects. Most people should be familiar withmagneticfields from playing with magnets as children: the forces of attraction or repulsion that act across open space between two or more magnetic...

it was possible for a changing electric field to create a changing magnetic field which would then create another changing electric field, and so on. This cause-and-effect cycle could continue, ad infinitum, with fast-changing electric and magnetic fields radiating off into open space without nee...
