WebHere the magnetic field of the compass needle is influenced by the magnetic field of the earth. When current flows in the wire the compass needle moves. It does so because the magnetic field of the wire is considerably stronger than the magnetic field of the earth. Detection The Earth's magnetic field strength was measured by Carl Friedrich Gauss in 1832 and has been repeatedly measured since then, showing a relative decay of about 10% over the last 150 years. The Magsat satellite and later satellites have used 3-axis vector magnetometers to probe the 3-D structure of the … See more Earth's magnetic field, also known as the geomagnetic field, is the magnetic field that extends from Earth's interior out into space, where it interacts with the solar wind, a stream of charged particles emanating from the See more At any location, the Earth's magnetic field can be represented by a three-dimensional vector. A typical procedure for measuring its direction is to use a compass to determine the direction of magnetic North. Its angle relative to true North is the … See more Short-term variations The geomagnetic field changes on time scales from milliseconds to millions of years. Shorter time scales mostly arise from currents in the … See more Animals, including birds and turtles, can detect the Earth's magnetic field, and use the field to navigate during migration.

WebSo the force from current 2 on wire 1 of length L1, from here to here, is equal to current 1 times L1-- which is a vector-- cross the magnetic field created by current 2. And so we can do the same cross product here. Put our index finger in the direction of L1. That's what you do with the first element of the cross product.
