What happen when two streams of electron move parallel to each other in the same direction?
attract each other
repel each other
cancel each other's electric field
cancel each other's magnetic field
Equivalent to currents in same direction. They repel each other.
Two like magnetic poles :
(a) repel each other
(b) attract each other
(c) first attract each other, then repel
(d) neither attract nor repel.
Q1.how does a moving electron creates magnetic as well as electric field and in what way these two fields are different from each other?
