1 1 Magnetic Fields Produced by Electric Currents: The Biot- Savart Law Jean-Baptiste Biot (1774-1862) This lecture: 29.1-29.3 For next time: HRW 29.4-29.6 The time after that: Midterm Review Next Monday, sample midterm review, 4:40 in 117 Osmond 2 Phys 212: Midterm 2 Information Wed, April 2 6:30 pm-7:45 pm Locations (by Phys212R sections): 1–6: 010 Sparks 7–13: 121 Sparks 14–28: 100 Thomas Material covered -- HRW: Chapters 26 through 29 20 questions, multiple choice Numerical data and relevant formulae provided Allowed to bring a double-sided 8.5”x11” paper with handwritten notes Standard scientific calculators ok; no palm computers, organizers or communication devices Conflict exams IMPORTANT : If you have a conflict with the scheduled exam time, you must fill out the conflict exam request form on the course website, in the exam section. The Deadline for conflict registration: 5 pm Wednesday, March 26 rd The HW is due (as usual) on Monday night of the week of the exam; no HW is due the week after the exam. 3 Last Time B due to wires: the Biot-Savart Law Loops Long straight sections Force between current carrying wires Today E and B fields act simultaneously on moving charges. They can be made to balance each other. B fields exert forces on current carrying wires, and torques on current loops A current loop has a magnetic dipole moment 4 Example: Force on a Current Carrying Wire What’s the force on this wire?
