Noise is generated by the inrush current into the solenoid.
Literal
Solenoid [to-への] inrush-current [by-で] noise [subject-が] is-generated.
An electrical engineering sentence. ソレノイド (solenoid) and ノイズ (noise) are both technical loanwords. 突入電流 ('inrush current') is a compound: 突入 (rush into) + 電流 (electric current) = the surge of current when a circuit first engages. The particle sequence への at the start is the composite attributive へ + の: ソレノイドへの ('directed into the solenoid'), modifying 突入電流. で here is causal/instrumental — '[caused] by the inrush current.' 発生する ('to occur, to arise, to be generated') is a formal/technical verb for things coming into existence in a measurable or mechanical sense.
