SUMMARY
The energy of a toroidal solenoid with 600 loops, an inner radius of 200mm, an outer radius of 240mm, and a height of 40mm is calculated to be 4.08J, with a current of 6.44A flowing through it. The cross-sectional area (S) is determined to be 0.0016m², while the adjusted area (S0) is 0.00176m². The initial attempt to calculate energy using the formula W0=B0²*S0*l0/2*μ0 yielded an incorrect result of 1.51J. The correct energy calculation formula used was W=B*H*S*(l-l0)/2, leading to the final energy value of 4.76J.
