A conducting loop carrying a current 
is placed in a uniform magnetic field pointing into the plane of the paper as shown. The loop will have a tendency to
A
contract
B
expand
C
move towards + ve 
-axis
-axis D
move towards -ve 
-axis
-axis
Text Solution
Verified by ExpertsThe correct answer is:
B
Applying Fleming's left hand rule, if magnetic field is perpendicular to paper inwards and current in the loop is clockwise, the magnetic force 
on each element of loop is radially outwards and loop has tendency to expand outwards.
Also, when a current carrying loop is placed in uniform magnetic field, then net force on it is zero and loop cannot have translational motion.
