Explanation :
When a person is sliding with constant velocity, the forces that are acting on him are :
(1) Weight, W = mg where g is acceleration due to gravity.
(2) Friction forces acting opposite to the direction of motion.
(3) Normal force.
The forces acting on the person is balanced because the person is sliding with constant velocity.
From figure it is clear that, friction force is balanced by and normal is balanced by
.
To solve this problem it is necessary to take into account the concepts related to the magnetic moment and the torque applied over magnetic moments.
For the case of the magnetic moment of a loop we have to,
Where
I = Current
A = Area of the loop
Moreover the torque exerted by the magnetic field is defined as,
Where,
I = Current
A = Area of the loop
B = Magnetic Field
PART A) First we need to find the perimeter, then
The total Area of the loop would be given as,
Substituting at the equation of magnetic moment we have
Therefore the magnetic moment of the loop is
PART B) Replacing our values at the equation of torque we have that
Therefore the torque exerted by the magnetic field is
