A semicircular wire of radius R, carrying current i, is placed in a magnetic field as shown in figure. On left side of X'X, magnetic field strength is B0, and on right side of X'X,magnetic field strength is 2B0. Both fields are directed inside the page.The magnetic force experienced by the wire would be
detailed solution
Correct option is C
The part AUB of the wire can be replaced by straight wire AB and BWC can be replaced by BC.Force experienced by AB is F1=iB0(2R) Force experienced by BC is, F2=i×2B0×2RResultant magnetic force acting on the wire is,F=F12+F22=10IB0RTalk to our academic expert!

Two horizontal parallel straight conductors, each 20 cm long, are arranged one vertically above the other and carry equal currents in opposite directions. The lower conductor is fixed while the other is free to move in guides remaining parallel to the lower. If the upper conductor weighs 1.0 g, what is the approximate current (in A) that will maintain the conductors at a distance 0.50 cm apart?
