Force on a Magnet in Lenz's Law

[andrevdh]

No the product E_magn*ΔV gives you the amount of magnetic energy in the small volume
and not the difference in energy. E_magn is the amount of magnetic energy in one unit of volume.

 

[Hesch]

E_magn has the unit [ J/m³ ]

ΔV has the unit [ m³ ]

Thus

E₂ - E₁ = E_magn * ΔV

has the unit [ J ]. Why do you continue this discussion ?
