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

THE RELATIONSHIP OF ELECTRIC FIELD INTENSITY AND ITS DISTANCE FROM THE CHARGED OPOINT PHYS-232 JIANSONG HE GROUP: Abstract This experiment was performed to find the electric field strength from different distance to the charged point. The field strength was determined statically‚ by measuring its electrical potential when subjected to loading‚ and dynamically‚ by measuring the electrical potential at different location on the conductive paper. The electrical potential was measured from three
