Abstract
We performed micromagnetic simulations regarding the detection of magnetic microbeads using a planar Hall effect sensor. The interactions between the magnetic particles and the sensor have been considered in order to simulate the behaviour of these systems. Our results show a high dependence of the sensor response on magnetic beads position. In order to have a linear response, a setup for magnetic biasing the sensor is proposed.
