Expert Answer:
When two protons are travelling parallel to each other, they will repel each other.
We know that when charges/current flows in the same direction in two wires, there is an attractive force between the two.
Hence, there should be magnetic attraction between the protons.
But, if we apply relativity concepts to the scenario, then the protons moving parallel to each other would see each other as stationary charges in their reference frame. Hence, electrostatic repulsion will take over the two and net force on the protons will be repulsive.

- Two wires carrying equal and opposite current are twisted together to reduce magnetic effect. What is the basis for this procedure?
- Two infinitely long parallel conductors carrying current in the same direction tend to attract each other. Derive the expression for the force per unit length.
- Two long parallel straight wires M and N separated by a distance 8 cm in the air carry currents 10 A and 12 A in opposite direction. Calculate the magnitude and direction of the force on a 22 cm length of wire N.
- What will happen if two linear current carrying conductors of unequal length are held parallel to each other?
- Two charges 5 C and 8 C separated by a distance of 10 cm are moving with velocity 15 m/s and 20 m/s respectively. What is the magnitude of force acting between these two charges?
- If two long parallel wires are suspended freely. What would be the effect if they are connected to a battery a) In series b) In parallel
- A rectangular loop of sides 20 cm × 10 cm carries a current of 10 A. Suppose the longer side of the rectangle is placed parallel at a distance of 5 cm to a conductor carrying 15 A current.
- A long straight conductor AB carries a current of 50 A and is fixed horizontally. Conductor CD lies parallel to AB at a distance of 5 cm in air. If CD carries a current I, calculate its magnitude of which it balances the weight of the conductor CD (Considering mass per unit length for conductor CD is 10-2 kg/m)
