FORCE ON A CURRENT CARRYING CONDUCTOR IN A MAGNETIC FIELD
JUSTIFICATION FOR FORCE ON A CURRENT CARRYING CONDUCTOR PLACED IN A MAGNETIC FIELD: Force on a current carrying conductor set in a magnetic field is because of the collaboration(interaction) of two magnetic fields. One is because of the current conveying component creates its own magnetic field around it. Other one is the outer(external) magnetic field.…
