Answer: 77.0J
Explanation:
The magnetic field is given as 4.40T
Since the volume is not given, we assume that the volume is 10.0cm³
We need to find the magnetic field energy in this volume.
The energy density is:
u = B²/2u•
u• is given as 4π × 10^-7 T.m/A
Using this formula we substitute
u = B²/2u• = (4.40 T)²/ 2(4π × 10^-7 T.m/A) = 7.704 × 10^6 J/m³
The energy is equal to the energy density multiply by the volume. You get;
U= uV = (7.704 × 10^6 J/m³) × (10.0 × 10^6m³) = 77.0J
