A square loop, carrying a steady current I, is placed in a horizontal plane near a long straight conductor carrying a steady current at a distance d from the conductor as shown in the figure. The loop will experience
- Option 1)
A net repulsive force away from the conductor
- Option 2)
A net torque acting upward perpendicular to the horizontal plane
- Option 3)
A net torque acting downward normal to the horizontal plane
- Option 4)
A net attractive force towards the conductor
Answers (1)
Force between two parallel current carrying conductors -
- wherein
I1 and I2 current carrying two parallel wires
a-seperation between two wires
Since magnetic moment and field both are parallel hence torque=0
But there will be an attractive force becuase of parallel current between wire and loop will attract more than repulsive force between anti parallel currents
Option 1)
A net repulsive force away from the conductor
This solution is incorrect
Option 2)
A net torque acting upward perpendicular to the horizontal plane
This solution is incorrect
Option 3)
A net torque acting downward normal to the horizontal plane
This solution is incorrect
Option 4)
A net attractive force towards the conductor
This solution is correct
