two wires are parallel to each other,carries current of same magnitude, and the distance between them is 10cm ,, wire A carries current out of the page ,, Wire B carries current into the page ... A compass is placed at 4 cm from wire A .. Where does the needle point ?
I also would like to know where does the needle will point if the two wires carries same current direction
same current direction - Attraction
opposite current direction - Repulsion
The Attempt at a Solution
I drew the magnetic field around each wire(Wire A-Anticlockwise ... Wire B-Clock wise) , but since the field is circular around a straight wire , so I couldn't know where it will point exactly .
