          Yes. The energy expended in producing the magnetic field can be recovered during the field's collapse, which occurs after the current producing the field is shut off.



          For example, the amount of energy stored in the superconducting magnets that steer the particle beams in CERN's Large Hadron Collider is equal the the kinetic energy of a fully-loaded jumbo jet going 500 MPH. Shutting the magnets down requires dissipating all that energy, and if anything goes wrong during that process, parts of the collider will get blown to pieces in an instant.



          Note that the energy stored in the magnetic field of a superconducting magnet did not get there for free. When running, those magnets and the machinery needed to support them consume as much electrical power as a small city, for which CERN pays the bill.

            @Barfieldmv Heating the supercooled magnets also blows them up (if not done in a controlled and slow way). That's what happened back in 2008 when it was first turned on and it took two years to fix.

            the net energy from a lightning strike isn't big enough to justify the cost of collecting it. because of the huge amount of bother in maintaining the liquid helium for the superconducting magnets, I see them as appropriate only in research and experimental settings. this would change when high-temperature superconductivity becomes real.

                    2 $begingroup$ Consider the function defined in (1) below related to the fundamental prime counting function $pi(x)$ . Note that A143519(n) is not multiplicative. (1) $quad f(x)=sumlimits_{n=1}^{x}A143519(n)$ https://oeis.org/A143519 The following plot illustrates $f(x)$ defined in formula (1) above. Figure (1) : Illustration of $f(x)$ defined in formula (1) The integer zeros of $f(x)$ for $xle 10,000$ are listed in (2) below. (2) $quad$ {1,6,9,12,19,30,79,80,81,116,193,201,287,288,291,668,673,679,680,685,686,1109} The zero crossings of $f(x)$ for $xle 10,000$ where $f(x)$ doesn't settle at zero are listed in (3) below.
