Electromagnetic Radiation Exercises

 

Constant Velocity shows variations on a positively charged particle moving with constant velocity.  The electric field vectors and magnetic field lines for a particle moving at constant velocities varying from v = 0 to v = 0.99 c are shown in the xy plane

Watch the animations, varying the velocity of the point charge from v = 0 to v = 0.99 c.  The animation takes one time step to calculate the proper field vectors and field lines for the point charge. 

 

~~1. Describe the electric field vectors and magnetic field lines in the xy plane as the velocity increases. 

 

~~2. The draw the electric field lines from the electric field vectors in the xy plane.  What do you notice about these lines as the velocity increases?

 

~~3. The draw the magnetic field lines in the yz plane.

 

~~4. Predict what would happen if the velocity of the point charge would suddenly change.
