Results of the Magnetic Properties Experiment on the Mars Pathfinder Lander

The ramp magnet is a 10x10 cm magnet mounted at the far end of the ramps used by the Sojourner Rover to depart from the lander. These magnets were optimized to give a large signal to noise ratio when measuring the elemental composition using the Alpha Proton X-ray spectrometer (APXS) mounted on the Rover. The average magnetic field strength and field gradient of the ramp magnets are between those of magnets 3 and 4 of the magnet array.
