Document Summary
To observe and visualize magnetic fields and forces. To study the motion of a charged particle in a magnetic field. To evaluate the magnetic force on a current-carrying conductor. To determine the force and torque produced with a magnet and current-carrying loop of wire (the dc motor). To study the fields generated by long, straight conductors. To observe the changes in the field with the conductor in loops (forming the solenoid). To calculate the magnetic field at selected points in space. To understand magnetism via magnetic moments. magnetic compass. The name magnet comes from lodestones found in a place called magnesia. A piece of intensely magnetic magnetite that was used as an early form of. Only magnetite with a particular crystalline structure, lodestone, can act as a natural magnet and attract and magnetize iron. In china, the earliest literary reference to magnetism lies in a 4th century bc book called.
