PPT-In order to generate the magnetic field as depicted, in which direction must the current

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. 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 Consider a uniform magnetic field into the board, with conducting rod moving through it:.  . + side. - side.
