Magnetic field due to currentHard
Question
A conducting wire bent in the form of a parabola y2 = 2x carries a current i = 2A as shown in figure. This wire is placed in a uniform magnetic field 
= -4
Tesla. The magnetic force on the wire is (in newton)
= -4 Tesla. The magnetic force on the wire is (in newton)Options
A.- 16 î
B.32 î
C.- 32 î
D.16 î
Solution
Leffective = AB = 4j
∴
= ILeff B = 2.4 ĵ × 4(-
) = - 32 î N
∴
= ILeff B = 2.4 ĵ × 4(-) = - 32 î NCreate a free account to view solution
