Suppose that the dipole moment associated with an iron atom of an iron bar is 1.7 × 10^-23 J/T. Assume that all the atoms in the bar, which is 7.0 cm long and has a cross-sectional area of 1.1 cm², have their dipole moments aligned. (a) What is the dipole moment of the bar? (b) What torque must be exerted to hold this magnet perpendicular to an external field of 2.0 T? (The density of iron is 7.9 g/cm³ and its molar mass is 55.9 g/mol.)

What is the formula to calculate the dipole moment of a magnet? This is the information I have, we used a wire that weighs 20.33 g with .1v and .94 amps running through it? The length of the magnet is 20mm, there was a 1cm deflection west, there was .45 cm between magnet and wire, and we were 5 degrees from earths magnetic field? Am I missing any information? Can you give me a general equation to find the dipole...

The torque (T) that is exerted on a magnetic dipole moment (μ) depends on the orientation of the magnetic dipole moment. Rank the three loops of wire carrying current shown in (Figure 4) in order by the magnitude of the torque exerted on them. Rank the magnitude of the torque exerted on the loops from greatest to least. If two loops have the same magnitude of torque, place one on top of the other.
