The examples provide a deep insight into the concept of the magnetic force and also the power of the integral. 0 answersPost by yasser algoufily on December 2, 2010This is really great, you guys are the best.I like how he solves practical examples after illustrating the physical concepts of the lesson.

### Magnetic Force on a Current Carrying Conductor

• A magnetic field exerts a force on a conductor carrying a current. If the wire is straight, and the field is uniform, the force is given by F = I L x B, where I is the current, L is a vector whose magnitude is the length of the conductor and whose direction is the same as the direction of the current, and B is the magnetic field vector.
• If the shape of the wire is arbitrary, the force on a segment ds of the wire is dF = I ds x B. The total force on the wire is obtained by integrating dF over the length of the wire.
