Episode 412: The force on a conductor in a magnetic field Having reminded your students that magnetic fields can be found near permanent magnets and in the presence of an electric current, the next step is to show how the ‘field’ can be quantified. Again, students should know that a conductor carrying a current in a magnetic field will experience a force and will probably remember that Fleming's Left Hand Rule can be used to find the direction of that force. Summary Demonstrations:

How works a Maglev train? A brief review of magnets will help explain how maglev (magnetic levitation) trains work. Every magnet has a north pole and a south pole. Similar poles of two magnets repel each other; opposite poles attract each other. These principles govern the levitation of maglev trains. Permanent magnets are always magnetic. Electromagnets are magnetic only when an electric current flows through them. The north and south poles of an electromagnet are related to the direction of the

Having left a decade long career to pursue my aspirations to work in the human resources field, I have personal and professional experiences that directly relate to the Massachusetts Institute of Technology research study “Reinventing Employee Onboarding”. The authors presented this argument with a focus on the field of human resources and more specifically the specialization of onboarding practices, which follows the criteria for an argument based in the technical sphere. The research shows that

electric potential to sketch lines representing the electric field produced by electric charge. Finally, we had to describe how the field from lines of charge differs from that produced by point sources. The electric field is identified by a capital E and at a certain point it equals the force on a test charge divided by the amount of the charge (E=F/g). In other words, the electric field is the surrounding charges which create an electric field around a given point. Theory: Equipotential lines provide

The most commonly accepted origins of magnetism is from a Greek legend. In an area of Northern Greece about 4,000 years ago, an elderly shepherd named Magnes was herding his sheep when he quickly noticed that he and his metal staff were stuck to the ground. He eventually got himself unstuck and looked to find the source of the attraction by digging up the ground around where got stuck. He found lodestones which contain magnetite which was a naturally occuring magnet. The stones were named after Magnes

kept during the entire process. Griffey, for example, never told Seattle upfront what his issues were. Seattle assumed it was money, but, in reality, Griffey wanted to be closer to his home and family. He refused to comment on the luxurious Safeco Field built in Seattle in order to avoid misleading people about his future. However, this secrecy backfired as his indifference caused major unrest in Seattle. Also, Griffey’s silence made it harder for the general managers to develop a solid strategy for
