Magnetic Fields PHY 114 Lab Report 10/23/2013 Abstract: The purpose of this experiment was to surrounding a magnet there is a magnetic field. The magnetic field is analogous to the electric field that exists in the space around electric charges. Like the electric field‚ the magnetic field has both a magnitude and a direction. The direction of the magnetic field at any point in space is the direction indicated by the north pole of a small compass needle placed at that point. Since electric

.INTRODUCTION Magnetic levitation is the latest in transportation technology and has been the interest of many countries around the world. The idea has been around since 1904 when Robert Goddard‚ an American Rocket scientist‚ created a theory that trains could be lifted off the tracks by the use of electromagnetic rails. Many assumptions and ideas were brought about throughout the following years‚ but it was not until the 1970’s that Japan and Germany showed interest in

Earth’s Magnetic Field Introduction Earth’s magnetic field is one of the world’s most complicated features. It started to be observed in 1845 by a scientist named Carl Friedman Gauss (Sarfati). The magnetic field is generated inside of the earth’s core and there are many scientists who still debate over how it was first created. There are also many arguments about the many changes that the field has gone through in it’s existence. These arguments are mostly either for a young-earth model or

Explain what it means when we say a substance is magnetic. A substance can be picked up by a magnet. Discuss the relationship between electric and magnetic fields. The magnetic field will be perpendicular to the electric field and vice versa Before you begin your lab‚ you need to form a hypothesis that reflects which material‚ voltage‚ and number of winds you think will produce the strongest electromagnet. Record your hypothesis as an if then statement. If I use copper‚ 100 volts‚ large thickness
