PPT-Earth’s Magnetic Field

Magnetosphere Earths 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. 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.

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. 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..
