The problem involves calculating the magnetic-field energy in a specified volume where the magnetic field strength is given as B = 3.50T. The context is rooted in electromagnetism, specifically focusing on magnetic energy density and its relation to total energy.
The discussion is ongoing, with participants clarifying the difference between energy density and total energy. Some guidance has been offered regarding the calculation process, specifically the need to multiply the energy density by the volume to find the total energy.
There is a concern about the correctness of calculations and the limited number of submissions available for the original poster, which may impact their approach to resolving the problem.
Should an answer using that formula along with those units be correct, though? I only have 2 more submissions available.phyzguy said:It doesn't ask for the energy density, which is what you gave. It asks for the energy, so your final answer should be in Joules, not Joules/m^3.
Yes, you're on the right track. You have calculated the energy density almost correctly. I got 4.87*106 J/m3, so one of us made a mistake. Then how do you go from energy density to energy?Jack_M said:Should an answer using that formula along with those units be correct, though? I only have 2 more submissions available.
