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.
Magnetic-field energy is the potential energy stored in a magnetic field. It is a form of energy that results from the movement of electrically charged particles.
Magnetic-field energy is measured in units of joules (J) or ergs (erg). It can also be measured in units of tesla (T) or gauss (G) for the strength of the magnetic field.
Magnetic-field energy is used in a variety of everyday devices such as electric motors, generators, and transformers. It is also used in medical imaging machines like MRI scanners and in various industrial processes.
Magnetic-field energy and electromagnetic waves are closely related. Electromagnetic waves are made up of oscillating electric and magnetic fields, and the energy of these waves is carried by the electric and magnetic fields.
Yes, magnetic-field energy can be converted into other forms of energy. For example, when an electric motor is powered by a magnetic field, it converts the magnetic-field energy into mechanical energy to produce motion.
