WebOct 28, 2024 · This arrangement of four coils per axis is called a Braunbek coil, a modified and improved Helmholtz coil developed in 1934 by Werner Braunbek. Each of the four coils has the same number of windings and the coils are connected in series, the same current flowing through all four coils.
WebThe configuration is called an improved Helmholtz or Maxwell Coil when a third coil is added. Not only does the magnetic field volume increase, but the magnetic field flux density is also further amplified. The amplification factor for a Helmholtz coil is about 50%. For a Maxwell coil, this increases up to 90%. food guernsey wyWebNov 18, 2016 · It's easy -- just use finite element analysis (FEA) software and simulate your coilgun.
