Why is there force on a current carrying conductor?

  1. Apr 20, 2014 #1
    I know that charges experience a force when they are moving with respect to a magnetic feild , but in case of conductor how is the force on the freely flowing electrons transferred to the structure of the conductor?

    The electrons aren't freely flowing. They're bound to the metal lattice. And as they drift, they interact sufficiently quickly with the lattice to transfer their momentum to it.

    Electrons do tend to move towards one side of the conductor. This produces a transverse potential difference which impedes further such motion. This potential difference can be measured, and is known as the Hall effect:

    As the electrons get pushed to the side, a positive charge (from the lattice) is left behind. The electrostatic field created allows the magnetic force to be "transferred" to the lattice.
