Two proton beams going in the same direction repel each other whereas two wires carrying currents in the same direction attract each other. Explain.

A

potential difference between them

B

mutual inductance between them

C

electric force between them

D

magnetic force between them

Text Solution

Verified by Experts

The correct Answer is:
D
The parallel wires carrying current in the same direction attract each other because mangnetic forces on the two wires each other.
