Two circular loops of current parallel to the z = 0 plane are arranged to form a Helmholtz coil. The center of one loop is at (0,0,0) m, and the center of the other loop is at (0,0,4) m. The radius of each loop is 2 m, and each loop carries a current of 5 A in the abφ direction. Find the magnetic field at (a) (0,0,0) and

i think it because equal matrices have equal dimensions, only square matrices can be symmetric. for all indices and . every square diagonal matrix is symmetric, since all off-diagonal elements are zero. in linear algebra, a real symmetric matrix represents a self-adjoint operator over a real inner product space.

because if the tool that you are using is not balanced it there would be false mass.

answer is slate

hope this
