Suppose that the magnetic field in some region has the form B = kz ˆx (where k is a constant). Find the force on a square loop (
AleksAgata [21]

Answer:

F = ika^2

Explanation:

As we know that loop is placed in YZ plane and magnetic field is along x direction

So here net force on the side of the loop which lies along Y axis is given as

F_1 = i (\vec L \times \vec B)

here we know that on Y axis z = 0

so B = 0

so we have

F_1 = 0

now on the opposite side we have z = a

so magnetic field is given as

B = ka

so force on that side is given as

F = i(\vec L \times \vec B)

F = i(a)(ka) sin90

F_2 = ika^2

so net force on the loop is given as

F = F_1 + F_2

F = ika^2
