Magnetic field due to currentHard
Question
A circular arc carrying current I is placed in uniform magnetic field B as shown in diagram. then force on arc is :-
Options
A.BIR tan α
B.2BIR cos(α/2)
C.2BIR sin(α/2)
D.None of these
Solution
= Rsin 
+ Rsin
= 2Rsin
(B ⊥ L)
= BI 
= 2BI R sin α/2 Create a free account to view solution
