Question

How to find the net magnetic dipole moment in a current carrying loop in the form of a cuboid.i wanted to post the diagram but i dont see an option here.plz....i hope u understand my question. there's a hollow cuboid ,current is flowing through its boundaries..through all faces leaving 2 faces.plz.tell me the method of how to find it

Answer 1

In the most general case of an arbitrary current distribution in space, the magnetic moment of such a distribution can be found from the following equation:

$$\mathbf {m} = \frac {1}{2} \int \mathbf {r} \times \mathbf {J} \, \mathrm{d} V,$$

SO, you need to use this formula to calculate the dipole moment, at the center of the cuboid it will be zero.
