Interplanetary magnetic field

The Interplanetary magnetic field, or more currently the heliospheric magnetic field (HMF), is the magnetic field that encompasses the entire solar system and all bodies within it. This massive field that permeates the solar system is generated and dragged out by the solar wind that flows outward from the sun at several million miles per hour. While the HMF typically deflects around Earth's magnetic field, the HMF can sometimes "reconnect" with Earth's field, allowing solar wind energy to funnel directly into the Earth's protective magnetospheric bubble.
