Abstract
Methods and tools for modifying magnetic tilt angle using a magnetically anisotropic material are disclosed. An electromagnetic logging tool includes an antenna coil oriented at a physical tilt angle relative to a longitudinal axis of the tool and a magnetically anisotropic material that modifies a magnetic tilt angle of the coil relative to the physical tilt angle a coil tilted at a physical tilt angle relative to an axis of the tool.
