Physics Question on Electromagnetic induction
A conducting loop carrying a current I is placed in xy plane . A uniform magnetic field pointing into Z direction is switched on. The loop will have a tendency to
A
contract
B
expand
C
move towards + ve x-axis
D
move towards -ve x-axis.
Answer
expand
Explanation
Solution
Using Fleming's left hand rule the circular conductor experiences radially outward force at every point of the conductor, so the loop will expand.
