Explain why a current carrying conductor placed in a magnetic field experiences a force

• The current sets up magnetic field around the wire.
• When the field due to current interacts with external magnetic field, the resultant magnetic field has greater flux density on one side than the other; in the diagram above, high flux density is created below than above.
• The Force on the wire is from a region of greater to lower flux density; thus it move up in this case
