JEE Main
JEE Main 2021
Moving Charges and Magnetism
A
Loop assumes circular shape with its plane normal to the field.
B
Loop assumes circular shape with its plane parallel to the field.
C
Wire gets stretched to become straight.
D
Shape of the loop remains unchanged
Solution:
Every part $(d\ell)$ of the wire is pulled by force $i ( d \ell) B$ acting perpendicular to current $\&$ magnetic field giving it a shape of circle.
