Monday, May 30th/2011 Magnetism and Electromagnetism

Today in class we have read pages 20-23 on Electromagnetism. We learned that an electric current can create a magnetic force that would be perpendicular to the electric current. We learned that the strength of a magnetic field is proportional to the current when the wire is straight. We learned how to find the direction of the magnetic field on a straight wire, when given the currents direction, by using the first right-hand rule. We also learned how to work with wires that are wrapped in loops (solenoid), by using the second right-hand rule. We were given
electromagnetism assignments to finish and tomorrow we will work on the physics lab worksheet we have, in class!
The next scribe will be Ahmed!
