KCET · Physics · Magnetic 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
- A zero
- B perpendicular to the plane of the loop
- C in the plane of the loop, away from the centre
- D in the plane of the loop, towards the centre
Answer & Solution
Correct Answer
(B) perpendicular to the plane of the loop
Step-by-step Solution
Detailed explanation
As shown in the following figure straight wire is placed parallel to the magnetic field produced by circular current. Hence, force on wire \(\mathrm{F}=0\) \((\because F=\sin \theta)\)
