- 9) Draw a nice uniform Magnetic field below. (This is the kind you might find in the center of a long solenoid.) Then place a positive charge "q" moving at a velocity "v" in it. Indicate the direction of "v" and draw the direction of the magnetic force vector on the moving charge.Dřaw the magnetic field, using arrows to indicate the direction of the mågnetic field. maignetie trerd. 8. to Dual Loop 19 Solenoid 9. Using your knowledge of magnetism and the right hand rule, determine whether the solenoids (coils) will attract or repel each other. Be sure to draw in the field lines and label the North and South poles.
