PPT-Earth’s Magnetic Field

Chapter 14 Lesson 3 What is a Magnet A magnet is any material that attracts iron and materials that contain iron Magnetic Poles Any magnet has two ends a north and a south pole Magnetic poles that are alike repel each other. 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 Dipole Field.

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.. Section 30. Previously supposed zero net current.. Then. For a conductor, there can be non-zero net current. Now we suppose there is such.. Then. “Conduction” current density. Magnetization gives no contribution to net current, even though there is surface current.
