Our magnetic sensors are designed to accurately detect the direction and magnitude of external magnetic fields for compassing and magnetometry applications From discrete sensors for lowcost high volume applications to high performance solidstate com In addition magnetic fields create a force only on moving charges The direction the magnetic field produced by a moving charge is perpendicular to the direction of motion The direction of the force due to a magnetic field is perpendicular to the dir The tip can be adjusted allowing the user to measure fields that are parallel or perpendicular to the long axis of the sensor The Magnetic Field Sensor can be used for a variety of interesting experiments involving magnetic fields Measure and study ABSTRACTThe earliest magnetic field detectors allowed navigationover trackless oceans by sensing the Earth's magneticpoles. Magnetic field sensing has vastly expanded asindustry has adapted a variety Sarah Arveson. Magnetism. A charged particle will experience a force when placed in a magnetic field and given an initial velocity. This is given by the Lorenz force. where q is the charge of the particle in Coulombs, m is the mass of the particle in kilograms, v is velocity in meters per second, and B is the magnetic field in .

FLASHBACK: Sketch a stress-strain graph for a malleable materials and label a) the limit of proportionality b) the elastic limit c) the ultimate tensile strength d) the breaking point. ~Magnetosphere. Earth’s Magnetic Field. The Earth acts like it has a giant bar magnet buried in it.. The magnetic field of the Earth is caused by convections currents of the molten iron and nickel interior of the Earth. Investigate and describe that magnets can attract magnetic materials and attract and repel other magnets.. What is Magnetism?. Let’s . Explore. What happens if you put together two magnets?. Do they become stronger together? . Up. Down. Neither works.. In which direction should the current be traveling in the closed loop to generate the magnetic field at the center of the circle with the given direction?. counter clockwise. the Earth's magnetic field at a given location. Objetive. The . objective of the activity is to measure the magnetic field of the Earth . an . a given . area. The relation . between . maximum . and minimum . Introduction. Solar flares occur when energy is converted into x-rays ,heat & supersonic fluid motion.. Energy is stored in magnetic filed lines.. Electric field changes connectivity of magnetic field lines and the energy is released.. Open: Venus – solar wind. Closed: Venus – Venus. Draped: solar wind – solar wind. Magnetic fields guide ion and electron motions. The connectivity (topology) of these field lines helps us to understand how the upper atmosphere interacts with the solar wind..
