**Title: ***
Controlling the Magnetic Force: Basic Strategies and Applications to Magnetic Drug Targeting
*

**Abstract:**
Motivated by problems arising in magnetic drug targeting, we propose
to generate an almost constant Kelvin (magnetic) force in a target subdomain,
moving along a prescribed trajectory. This is carried out by solving a
minimization problem with a tracking type cost functional. The
magnetic sources are assumed to be dipoles and the control
variables are the magnetic field intensity, the source location and
the magnetic field direction. The resulting magnetic field is shown
to effectively steer the drug concentration, governed by a
drift-diffusion PDE, from an initial to a desired location with limited spreading.
