CONTENT QUALITY REQUIRED

A CONDUCTING CIRCULAR LOOP OF RADIUS r CARRIES A CONSTANT CURRENT. IT IS PLACED IN A UNIFORM MAGNETIC FIELD B IS PERPENDICULAR TO THE PLANE OF THE LOOP. THE MAGNETIC FORCE ON THE LOOP IS
a) i r B
b) 2 π ir B
c) zero
d) π ir B

Answer 1

Hey there! ☺☻☺

Given,
Radius = r carries constant current,
Magnetic field B is perpendicular to the plane of the loop.

Magnetic force will be zero because the net force is zero.

The net force is zero because when a current carrying loop in kept uniform magnetic field then the net force is always zero.

Hope It Helps You! ☺☻☺

Answer 2

A CONDUCTING CIRCULAR LOOP OF RADIUS r CARRIES A CONSTANT CURRENT. IT IS PLACED IN A UNIFORM MAGNETIC FIELD B IS PERPENDICULAR TO THE PLANE OF THE LOOP. THE MAGNETIC FORCE ON THE LOOP IS zero

Magnetic force will be zero because the net force is zero. ( c ) 

__________________________________________________________________________________--

.= >  the net force is zero because Velocity is constant and there is no net or unbalanced force.
