Typically, reducing the coil radius doesn’t change the magnetic field for long solenoids, but it will reduce the inductance and C P. Reducing C P will increase the self-resonant frequency.

U.S. Delivers 60-Foot ‘Monster’ Magnet to France - to Power the Heart of the ITER Fusion Reacto For a long time, humanity has looked to the stars not just with wonder, but with ambition. Among ...

Unlike the Earth, Mars does not have a strong, global magnetic field. ... could involve using a vast ground-based solenoid loop system. Solenoid loops are long, thin loops of wire, ...

The test also demonstrated that the CSMC could create a magnetic field of 5.7 Tesla, about 100,000 times stronger than Earth’s. It also reached a record for stored energy, reaching 3.7 megajoules.

When fully assembled, the central solenoid will be 59 feet (18 meters) tall and 14 feet (4.3 m) wide, and will be capable of producing a magnetic field measuring 13 teslas — around 280,000 times ...
