Electromagnetism

B and E Blocks in the process of finishing up their work with magnetism. E Block worked on two investigations that highlighted properties of electromagnets and permanent magnets. Students looked at how changing the number of coils affected the strength of an electromagnet and then used their magnetic field sensor to investigate properties of the magnetic field of a bar magnet. B Block will work on this lab tomorrow and used to day as review time for Thursday's exam. E Block gets their review tomorrow.

C Block conducted the same lab investigations as E Block, but also spent time with the last section of this chapter's material, which dealt with magnetic forces. You should be able to calculate the magnitude and direction of a force acting on a charged particle or current-carrying wire in a magnetic field and remember that your homework problems are due tomorrow (lab write-up not due until Friday). We'll go over last night's homework and tonight's homework tomorrow as part of the exam review.

F Block discussed the concept of electromagnetism, referring often to their lab investigation where they built and studied an electromagnet. Tomorrow, we'll hit magnetic forces, but, as discussed in class, really won't have time for a formal review. Make sure to prepare early and come to me with questions if you have issues.
