A magnet weighing 70 g has a magnetic moment of `2.4 Am^2`. If the density of the material is `6,800 kg//m^3` , find the intensity of magnetization.

Text Solution

AI Generated Solution

To find the intensity of magnetization (I) of the magnet, we can use the formula: \[ I = \frac{M}{V} \] where: - \( M \) is the magnetic moment, - \( V \) is the volume of the magnet. ...
