Sources of Magnetic Field II: Transcript
Physics 2415 Lecture 18 Michael Fowler UVa Todays Topics More about solenoids BiotSavart law Magnetic materials Ampères Law General Case Ampères Law states that for any magnetic field generated by a steady flow of electrical currents if we take an arbitrary closed path in space and integrate around it then . 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 Andrii Neronov.
