Magnetic Effects Of Current Question 217
Question: An arbitrary shaped closed coil is made of a wire of length L and a current I ampere is flowing in it. If the plane of the coil is perpendicular to magnetic field $ \overset{\to }{\mathop{B}}, $ , the force on the coil is [MP PMT 2001]
Options:
A) Zero
B) IBL
C) 2IBL
D) $ \frac{1}{2}IBL $
Show Answer
Answer:
Correct Answer: A
Solution:
As shown in figure, since $ \overrightarrow{L}=0 $ Hence according to $ \vec{F}=i(\vec{L}\times \vec{B}) $
Þ $ \vec{F}=0 $
