The force acts along the line joining the charges for Fe
The direction of magnetic force acting on any charged particles Q moving with a
uniform velocity U in a magnetic field B is orthogonal with U and B
Two like charges repel one another, whereas two charges of opposite polarity attract.
Its strength is directly proportional to the product of the magnitudes of the two
charges and inversely proportional to the square of the distance between them.
