- 1. Force Between Two Parallel Wires:
- 2. Ampere’s Law: Curl your right hand around the Amperian loop, with the fingers pointing in the direction of integration. A current through the loop in the general direction of your outstretched thumb is assigned a plus sign, and a current generally in the opposite direction is assigned a minus sign.
- 3. Ampere’s Law, Magnetic Field Outside a Long Straight Wire Carrying Current:
- 4. Ampere’s Law, Magnetic Field Inside a Long Straight Wire Carrying Current:
- 5. Example, Ampere’s Law to find the magnetic field inside a long cylinder of current.
- 6. Solenoids and Toroids: Fig. 29-17 A vertical cross section through the central axis of a “stretched-out” solenoid. The back portions of five turns are shown, as are the magnetic field lines due to a current through the solenoid. Each turn produces circular magnetic field lines near itself. Near the solenoid’s axis, the field lines combine into a net magnetic field that is directed along the axis. The closely spaced field lines there indicate a strong magnetic field. Outside the solenoid the field lines are widely spaced; the field there is very weak.
- 7. Solenoids: Fig. 29-19 Application of Ampere’s law to a section of a long ideal solenoid carrying a current i. The Amperian loop is the rectangle abcda. Here n be the number of turns per unit length of the solenoid
- 8. Magnetic Field of a Toroid: where i is the current in the toroid windings (and is positive for those windings enclosed by the Amperian loop) and N is the total number of turns. This gives
- 9. Example, The field inside a solenoid:
