Formula of Average Magnetic B Field Strength of Large Conductor

  1. Aug 13, 2015 #1
    Any one knows how to calculate the magnetic B field strength at a distance from a Large Conductor ? Do we go by average ?

    thanks

    Oh, and d is the distance from the center of the wire.

    I do believe he means the magnetic field strength due to the perm. magnet.

    In general, for an arbitrarily shaped magnet, this is difficult. One method would be to add up the magnetic dipoles over the volume, although I don't believe the value is given in a materials data sheet.

    Yes tou are right . I am going to calculate the EMF(v) later as the magnet will be in motion at the same distance as the above drawing .
    He magnet will be N35 or N52 but it can be of any force the formula should be able to handle any type,of magnet and it T strength . The magnet will be a ring and it will rotate on its axis at some kind of rpm . But still this things shouldn't effect the formula . Any per idea ?
