KCET2012PhysicsMagnetic Effects of Current
A straight current carrying conductor is kept along the axis of circular loop carrying current. The force exerted by the straight conductor on the loop is
Options
- Azero
- Bperpendicular to the plane of the loop
- Cin the plane of the loop, away from the centre
- Din the plane of the loop, towards the centre
Correct answer
B. perpendicular to the plane of the loop
Step-by-step solution
As shown in the following figure straight wire is placed parallel to the magnetic field produced by circular current. Hence, force on wire F =0( F= )
