Question:
Two long straight wires are parallel and 8.0 cm apart. They are to carry equal currents such that the magnetic field at a point halfway between them has magnitude 300μT.
(a) Should the currents be in the same or opposite directions?
(b) How much current is needed?
Step by Step Answer:
a The currents must be opposite or antiparallel so ...View the full answer

A magnetic field is a vector field that describes the magnetic influence on moving electric charges, electric currents, and magnetic materials. A moving charge in a magnetic field experiences a force perpendicular to its own velocity and to the magnetic field. The video shows the practical implications of magnetic force around different objects.
