how to find direction of magnetic field by compass?

How to find the direction of Magnetic field? Thumb rule

March 6, 2022April 9, 2021 by Mir

Scientist Hans Christian Oersted first observed the deflection of a magnetic needle or compass placed near a current carrying wire. This concludes that the current carrying wire can produce a magnetic field around it. In another article, we have discussed the Origin, definition, unit and dimension of magnetic field. Since, the magnetic field is a … Read more
