Is the Venusian magnetic field actually more powerful than the solar wind's magnetic field that induced it? I know that Venus' magnetic field is not due to Magnetohydrodynamic processes rather, it is induced via incoming solar wind which forms a bow shock and a magnetosphere, but is the magnetosphere stronger than the magnetic field of the solar wind particles
For example, in an transformer, analogy to Venus' magnetosphere, the transformer has a primary coil similar to solar wind, and a secondary one similar to the ionosphere. The solar wind is moving with a charge at ultra high speed which in turn creates a magnetic field, now this magnetic field comes close to the ionosphere and that due to Faraday's law of electromagnetic induction, then this current acts like an electromagnet and produces a magnetosphere via Ampere's law which fends off the solar wind, and prevents atmospheric escape. So is this a step up transformer or step down transformer (I'm not an mechanic, but the analogy to transformer was simple)
My second question is that, what are the tesla values of the magnetosphere vs solar wind? This will assist in deciding whether it is step up or step down, since different sources give different result
